Yale Residential YRD634 Pro 2 Deadbolt Keypad Lock, Bluetooth Technology, No Key Override

The YRD634 Pro 2 keypad deadbolt mounts on doors 1-3/8 to 1-3/4 inches thick, and it uses the standard residential deadbolt prep: a 2-1/8 inch cross bore through the face and a 1 inch edge bore for the bolt. If your existing deadbolt was drilled to that prep, the swap is a screwdriver job. Doors thicker than 1-3/4 inches are outside the range.

No key cylinder. The YRD634 is the no key override version, so entry is by code on the keypad or, with the Yale Access app in Bluetooth range, Auto-Unlock. That is the point of the model for some buyers (no cylinder to pick or bump), and a dealbreaker for others. If you want a mechanical key as a backup, this is not the model. Power loss is not a lockout risk: it runs on batteries, and if the batteries die you can jump it with a 9V.

Out of the box the YRD634 talks Bluetooth only, so app control works when you are within range of the door. It works with Apple HomeKit, and remote access through HomeKit needs an Apple TV or HomePod acting as a hub. For Alexa or Google, or for away-from-home control through the Yale Access app, you add a Yale Wi-Fi Smart Module. Matter and Z-Wave modules also drop into the same lock. All modules are sold separately, and that is the reason to buy this body rather than a fixed-radio lock: the radio changes, the lock does not.

The Delaney KP400 is an electronic deadbolt in Grade 2, the same grade the Yale YRD634 Pro 2 carries. The difference is how each one is operated remotely: the YRD634 uses a Bluetooth connection with a keypad reader, while the KP400 comes with a programmable remote. Both are deadbolt-format electronic locks, so both replace an existing deadbolt rather than a knob or lever.

The Yale YRD634 Pro 2 is built for residential use. For multihousing and hospitality openings, Dormakaba's 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 (ELO). Both read credentials by RFID card rather than by keypad code, which is what property-wide credential systems are usually built around.

For the same opening without electronics, the Dexter DB2000 single cylinder deadbolt is Grade 2 with a 1-3/8 inch to 1-3/4 inch door thickness range, matching the 1-3/8 inch to 1-3/4 inch range the Yale YRD634 Pro 2 covers. The Arrow DBX61 and the Cal-Royal CB160 are also Grade 2 single cylinder deadbolts in cylinder x thumbturn function. All three are key-and-thumbturn operation instead of a keypad, so there are no batteries, codes, or app to manage.

The Yale YRD634 Pro 2 is ANSI/BHMA Grade 2. Where a Grade 1 deadbolt is specified, the Dexter DB1000 single cylinder is Grade 1 with a 1-3/8 inch to 1-7/8 inch door thickness range, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset, and the Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt for 1-3/8 inch to 1-3/4 inch doors. These are keyed mechanical deadbolts, so code-based access is handled separately.

The Yale YRD634 Pro 2 covers 1-3/8 inch to 1-3/4 inch doors. For a thicker leaf, the Corbin Russwin DL3011 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch, and the Deltana 7312KA2 double cylinder deadbolt covers 1-3/8 inch to 2 inch. Both are keyed mechanical deadbolts rather than keypad units.

They are both code-entry deadbolts but they mount differently. The Yale YRD634 Pro 2 is a bored deadbolt that goes into a 2-1/8 inch cross bore with a 1 inch edge bore, so it drops into standard deadbolt prep. The Codelocks CL2200 is an electronic surface deadbolt, medium duty, and the CL2210 is an electronic mortise deadbolt. A surface or mortise unit does not use the same door prep, so it is not a drop-in swap for a bored deadbolt.

The Codelocks CL200 is a surface deadbolt with key override, so a mechanical key still opens it if the code path is unavailable. Among electronic deadbolts, the Dormakaba Saffire LX-D carries Electronic Lock Override (ELO). The Yale YRD634 Pro 2 is a Bluetooth keypad deadbolt with no key override, which is the tradeoff for having no exterior keyway to pick or drill.

The Yale YRD634 Pro 2 is a Bluetooth keypad deadbolt with no key override, so it does not join a mechanical keying system. Where an opening has to stay on the building keyway, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core, the Deltana CL200LAIC is a Grade 2 single deadbolt with interchangeable core and 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt. All three accept the core your system already uses.

The Pro 2 keypad deadbolt carries a 90 minute fire rating and is ANSI/BHMA Grade 2 certified. Grade 2 is the residential and light commercial tier, which matches how it is catalogued: a residential lock. For a heavier commercial opening you would step up to a Grade 1 deadbolt such as the Design Hardware D1 Series or the Corbin Russwin DL3011.

Yes, and this is where the Pro 2 keypad deadbolt earns its place on a rental door. You can share unlimited entry codes with family, tenants, or service people through the Yale Access app and track that access, so nobody is hiding a key under a mat. The keypad is matte to resist fingerprint wear patterns giving the code away, and two-factor authentication plus lost-phone handling covers the app side. Code sharing runs through the app in Bluetooth range unless you add a Wi-Fi module for away-from-home management.

Since the YRD634 has no cylinder, look at the Codelocks CL200 surface deadbolt, which is a code lock with key override, or the Dormakaba Saffire LX-D, an RFID electronic deadbolt with BLE and an electronic lock override. If you want an electronic deadbolt with a remote instead of an app, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. For multifamily RFID credentialing rather than codes, the Dormakaba Nova-D is the multihousing option.

Pair the electronic doors with a plain Grade 2 cylinder-by-thumbturn deadbolt on the interior or secondary openings. The Dexter DB2000 single cylinder covers the same 1-3/8 to 1-3/4 inch door thickness the Yale does, so the same door prep works across the building. Hager 3115 is another Grade 2 cylinder x thumbturn in that thickness range, and it is fire rated. Keep in mind the YRD634 itself has no cylinder, so it will not key alike with those mechanical bolts; the code list and the key system stay separate.

It is a residential lock, Grade 2, and Yale sells it for the home front door. On a commercial entrance with real traffic you want Grade 1 hardware: the Falcon D111 Grade 1 heavy duty deadbolt, the Cal-Royal CRB800 with a UL 3-hour fire rated latch, or the Corbin Russwin DL3211 for a 1-3/4 inch commercial door. Where a commercial opening needs electronic access, the Dormakaba Saffire LX-D or the DynaLock 1300 Series mortise electric deadbolt are the electronic paths.

The Yale YRD634 Pro 2 is a keypad deadbolt with no key override, so it is not a double cylinder lock. For keyed operation on both faces, the Dexter DB2000 double cylinder is Grade 2 for 1-3/8 inch to 1-3/4 inch doors, the Hager 3214 is a Grade 2 double cylinder deadbolt with Schlage C keyway over the same thickness range, and the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors.

The Yale YRD634 Pro 2 replaces the deadbolt alone, so the knob or lever below it stays as is. If the opening needs both in one assembly, the Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt, which operates latch and bolt together.

The bore fits the same standard deadbolt prep, but the certification is different. The Yale YRD634 Pro 2 is Grade 2. The Cal-Royal ED500 and LSD are Grade 3 single cylinder deadbolts covering 1-3/8 inch to 1-3/4 inch doors, with the LSD carrying an ADA ergonomic thumbturn. Where a spec calls out Grade 2 or better, a Grade 3 unit will not satisfy it.

Auto-Lock is built in and it is triggered by DoorSense, which senses that the door has actually closed rather than just running a timer. That distinction matters on a door that gets left ajar, since a timer-based lock will throw the bolt into the frame edge. Auto-Unlock is optional if you want the door to open as you walk up without touching the lock or your phone.

Three finishes on the YRD634: 613 Oil-Rubbed Bronze, 619 Satin Nickel, and BSP Black Suede Powder Coat. If you are standardizing a building and matching existing mechanical hardware, 619 Satin Nickel is the one that pairs with the common satin nickel and chrome-family trim already on most units. The lock body is metal.

The Yale YRD634 Pro 2 comes in 613 Oil-Rubbed Bronze, 619 Satin Nickel, and BSP Black Suede Powder Coat. For a mechanical deadbolt in a dark decorative finish on the same door, the Emtek #11 Tuscany is a lost wax cast bronze deadbolt in cylinder x thumbturn function.
