Yale Residential YRD420 WF1 0BP – Frequently Asked Questions
1) Do I need to buy a separate Wi-Fi module for the Yale YRD420, or is Wi-Fi built in?
The YRD420 is specified with Wi-Fi and Bluetooth connectivity, so remote access through the Yale Access app works without a separate radio purchase. The Assure Lock 2 platform is modular, and the base Bluetooth-only versions of it require a Wi-Fi, Matter, or Z-Wave Smart Module bought separately. If you are standardizing a building on remote access, order the Wi-Fi configuration rather than the plain Bluetooth model.
2) Can I swap my existing deadbolt for the Yale Assure Lock 2 without calling a locksmith?
It replaces a standard deadbolt on most US and Canada entry doors with just a screwdriver, no new boring needed on a normal prep. Practically, that means a property manager or maintenance tech can do the changeover in place. What you should confirm first is door thickness, since the lock is built for 1-3/4 to 2-1/4 inch doors, and the strike prep, which measures 1 x 2-1/4 inches.
3) Will the Yale YRD420 strike plate line up with the strike cutout already in my jamb?
The supplied strike is 1 x 2-1/4 inches, which is the common single deadbolt strike footprint on residential jambs. If your existing deadbolt uses that same size mortise in the frame, the new strike drops into the same pocket and you are only driving screws. A wider or T-strike jamb prep will leave exposed cutout that needs a filler or a larger plate.
4) Is the Yale Assure Lock 2 a keyed deadbolt or key free?
The YRD420 is the key free version: a touchscreen keypad and app entry, with no cylinder or keyway in the outside trim. That means no key to copy and nothing to pick, but it also means you cannot rekey it into an existing master key system. If you need a mechanical key override on the same door, choose a keyed Assure configuration or a conventional cylinder deadbolt instead.
5) What is a non-electronic deadbolt that fits the same 1-3/4 inch to 2-1/4 inch door as the Yale YRD420?
The Corbin Russwin DL3011 covers a 1-3/4 inch to 2-1/4 inch door thickness range, the same range the YRD420 Assure Lock 2 covers. The DL3011 is a Grade 1 cylindrical deadlock in a cylinder x blank configuration, so it is key-operated on one side with no thumbturn and no keypad. Most other deadbolts in the same family stop at 1-3/4 inch, including the Dexter DB2000 single cylinder at 1-3/8 inch to 1-3/4 inch and the Hager 3215 at 1-3/8 inch to 1-3/4 inch, so on a thick door the DL3011 is the one to confirm first.
6) What other electronic deadbolt works instead of the Yale YRD420 Assure Lock 2 on a multifamily or hotel door?
The Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. Both read a credential card rather than the touchscreen keypad the YRD420 uses, which is the usual dividing line: the Yale is a residential-rated lock driven by codes and the Yale Access app over Wi-Fi and Bluetooth, while the two Dormakaba deadbolts are built around issuing RFID cards to a rotating population of guests or tenants. If the property already runs a card system, the Nova-D or Saffire LX-D is the one to spec.
7) The Yale YRD420 is residential rated - what commercial Grade 1 deadbolt goes on the same opening instead?
The YRD420 Assure Lock 2 is a residential lock. For a commercial opening the Design Hardware D1 Series is a Grade 1 double cylinder deadbolt rated extra heavy duty for a 1-3/4 inch door, and the Falcon D111 is a Grade 1 deadbolt in classroom function with an adjustable backset, rated heavy duty. The Delaney LM Series is a Grade 1 single cylinder less core deadbolt, which suits a facility that keys its own cores. None of the three offer keypad or app entry; they are mechanical key-operated locks.
8) Which deadbolt do I use instead of a keypad lock on a fire rated door in a commercial building?
The Hager 3215 is a single cylinder deadbolt with a 1 inch throw carrying a fire rating, the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder that also carries a fire rating, and the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. All three take a 1-3/8 inch to 1-3/4 inch door in the Hager case. The YRD420 Assure Lock 2 is a residential lock, so on a rated opening one of these mechanical deadbolts is the one to price.
9) What looks like a deadbolt substitute for the Yale Assure Lock 2 but is only a component or accessory?
Three part numbers in the deadbolt family are not complete locks. The BEST 8T is a T Series tubular deadbolt tube component, the Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application, and the Dormakaba M1960 is an M1000 Series single cylinder deadbolt in cylinder x turn supplied with no trim. Ordering any of the three expecting a finished lock leaves the job short. The YRD420 Assure Lock 2 is a complete touchscreen deadbolt with a back-up key.
10) What happens to the Yale touchscreen deadbolt when the batteries die or the power goes out?
It runs on batteries, so a utility outage does not lock anyone out. If the batteries themselves run flat, a 9V battery held against the exterior contacts gives enough power to open the lock. On the key free model there is no cylinder to fall back on, so the 9V jump is the recovery method to plan for. Keep that in mind on units where you cannot get inside another way.
11) Is the Yale Assure Lock 2 rated for commercial use, or residential only?
It is classified as a residential product and is certified to Commercial Grade 2 for durability against everyday use and weather. That combination works for single family, multi-family units, and short term rentals. For a school, hospital, or government corridor door where a Grade 1 deadbolt is specified, look at a Grade 1 mechanical option such as the Corbin Russwin DL3011 cylindrical deadlock, which covers the same 1-3/4 to 2-1/4 inch thickness range.
12) I manage rental units and need code access for cleaners and contractors. Is a keypad deadbolt like the Yale Assure 2 the right choice over a keyed deadbolt?
For turnover access it is. You can issue unlimited entry codes through the Yale Access app and track who used which one, then delete a code when a tenant or vendor leaves, instead of rekeying cylinders. Auto-Lock with DoorSense relocks once the door is sensed closed, which removes the most common vacancy complaint. If you would rather not manage an app at all, a mechanical option like the Cal-Royal CB160 Grade 2 cylinder x thumbturn deadbolt is the straightforward keyed alternative.
13) What other electronic deadbolts are there if the Yale Assure Lock 2 is not the right fit?
Several, and they serve different jobs. The Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, a simpler standalone keypad with no smartphone platform behind it. For multihousing and hospitality where you are running credentials rather than phone apps, the Dormakaba Nova-D and the Saffire LX-D are RFID electronic deadbolts, the LX-D adding Bluetooth and an electronic lock override. Codelocks CL2200 is a surface mounted electronic deadbolt, useful where you cannot bore the door.
14) I need a second deadbolt on a thick 2-inch door but do not want electronics. What mechanical deadbolt covers that thickness?
Most residential deadbolts stop at 1-3/4 inches, so thickness is the limiting spec. The Corbin Russwin DL3011 Grade 1 cylindrical deadlock is rated 1-3/4 to 2-1/4 inches, matching the same range the Yale YRD420 covers. The Deltana 7312KA2 double cylinder Grade 3 goes 1-3/8 to 2 inches, which reaches a 2 inch door but no further.
15) Is there a keypad deadbolt simpler than the Yale Assure Lock 2 that does not need an app or a network?
The Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, so codes and the remote handle access without a phone app or a network connection. The Codelocks CL2200 is an electronic surface deadbolt rated medium duty, and the Codelocks CL2210 is an electronic mortise deadbolt. The YRD420 differs in that it is built around Wi-Fi and Bluetooth and the Yale Access app on top of its touchscreen keypad, so if nobody on site wants an app account, one of the three above answers the same door.
16) What deadbolt matches the Yale Assure Lock 2 on the other doors of the same house without adding a second smart lock?
For back doors and side entries that do not need code access, a mechanical single cylinder deadbolt keeps the look consistent. The Bravura 310RC Elite is a Grade 2 contemporary round deadbolt in cylinder x thumbturn, the Bravura 310SC Elite is the contemporary square version of the same Grade 2 deadbolt, and the Brinks Mendocino is a contemporary square single cylinder deadbolt with a four way adjustable backset. All three are keyed on the outside with a thumbturn inside, where the YRD420 uses a touchscreen keypad on the outside.
17) What should I use instead of the Yale Assure Lock 2 on a glass front or narrow stile door where a keypad deadbolt will not fit?
The Emtek 2050 is a European mortise deadbolt with an integrated roller latch in a square trim, and the Emtek 2051 is the round trim version of the same mortise deadbolt - both cylinder x thumbturn and both cut into the door edge rather than through a bored face, which suits a narrow stile. The Arrow 460 is a mortise lock strike with latchbolt and deadbolt functions and a straight lip for a 1-3/4 inch door if the frame side needs to be addressed at the same time. The YRD420 is built to replace a bored deadbolt on a standard entry door, so it does not carry over to that opening.
18) Is there a deadbolt like the Yale YRD420 that takes an interchangeable core so a facility can key it in house?
The Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core for a 1-3/8 inch to 1-3/4 inch door, the Deltana CL200LAIC is a Grade 2 single deadbolt with interchangeable core and a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt. All three ship without a core so the facility drops in its own keying system. The YRD420 is a key free touchscreen deadbolt whose access is managed through codes and the Yale Access app, with a back-up key included.
19) What is the difference between the Yale YRD420 Assure Lock 2 and a double cylinder deadbolt for a door with glass next to it?
A double cylinder deadbolt takes a key on both sides, so no thumbturn can be reached through adjacent glass. The Dexter DB1000 is a Grade 1 double cylinder deadbolt for a 1-3/8 inch to 1-7/8 inch door, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway for a 1-3/8 inch to 1-3/4 inch door, and the Baldwin Reserve Double Cylinder Contemporary Round is a double cylinder deadbolt in a round trim. The YRD420 is a key free touchscreen lock, so it operates from a keypad outside rather than a second cylinder.
20) What deadbolt works for an exit only door where the Yale keypad lock is more than the opening needs?
The Arrow E60 is a Grade 2 exit deadlock, non-keyed, in a blank plate x thumbturn configuration for a 1-3/8 inch to 1-3/4 inch door - there is no cylinder outside at all, so the door throws and releases only from the inside. The Callan 205S is a Grade 3 one-sided half-bore deadbolt, which needs only a partial bore. The YRD420 Assure Lock 2 puts a touchscreen keypad on the exterior face, which an exit only opening does not use.
21) What finishes does the Yale YRD420 Assure Lock 2 come in?
Three finishes: Oil Rubbed Bronze Permanent (10BP), Satin Nickel (619), and Black Suede Powder Coat (BSP). The Permanent bronze does not live-finish, so it stays consistent across a run of doors, which matters when you are matching a fleet of units rather than one entry. Satin Nickel is the closest match to standard 619/US15 lever and knob trim already on most doors.
22) Does the Yale Assure Lock 2 work with Apple HomeKit and Alexa?
HomeKit is supported directly, so the deadbolt can be managed from the Apple Home app or by Siri, with remote control once an Apple TV or HomePod is acting as a home hub. Amazon Alexa and Google are reached through the Wi-Fi Smart Module path on the platform. On the Wi-Fi configuration, remote app access is covered by the built in Wi-Fi and Bluetooth radios.
23) Is the Yale touchscreen keypad going to show fingerprints and give away my code?
The keypad is a matte touchscreen chosen specifically for fingerprint resistance, so wear patterns do not map out the digits. Yale layers two-factor authentication and biometric verification on top through the app for accounts, and lost phone handling if a credential goes missing. On an exposed front door that smudge resistance is the practical part.
24) Does the Yale YRD420 use the same strike as a standard mechanical deadbolt?
The YRD420 Assure Lock 2 uses a 1 inch by 2-1/4 inch door strike, the common face size on residential deadbolt strikes, which is why it replaces an existing deadbolt on standard US and Canada entry doors. Where a mortise lock is involved the strike is a different part: the Arrow 460 is a mortise lock strike with latchbolt and deadbolt functions and a straight lip for a 1-3/4 inch door, and it does not interchange with the YRD420 strike.
25) If I want a decorative deadbolt on the front door instead of the Yale touchscreen, what are the options?
The Emtek #11 Tuscany is a lost wax cast bronze deadbolt in cylinder x thumbturn, the Emtek 8323 Modern Disc is a brass double cylinder deadbolt, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt in the Estate Series with entrance function. All three are mechanical and trade the keypad and app control of the YRD420 for a finished decorative trim.
