Lockey GM270-B-V – Frequently Asked Questions

1) What do I need to specify when ordering a Lockey GM270 Gemini cabinet lock?
Two choices, and both are made at order time. Finish comes in black, silver, or white. Keypad direction comes in left handed horizontal, right handed horizontal, or vertical, and that is the one people get wrong: it sets how the wheels read on the cabinet, so decide which way the lock sits on the door before you order rather than after.
2) What happens if a tenant or an employee forgets the combination on a Lockey GM270?
There is a key way out. The GM270 Gemini carries an emergency key override on a 7-disc barrel, so a lost or forgotten code does not mean drilling the cabinet. It also has a code finding feature and a code change function, so once you are back in you can reset the combination without pulling the lock off the door.
3) Should I use a mechanical combination cabinet lock or a keyed cabinet lock for file cabinets my staff shares?
For shared access, a combination lock removes the key logistics. The GM270 Gemini is mechanical with 4 wheels and 10,000 possible combinations, so nobody carries a key day to day and you change the code when staff turn over. A keyed cam lock is the better answer when you want individually controlled access or want the cabinet on an existing key system: the Sargent 4142 horizontal cabinet lock uses a 6-pin brass cylinder, and the BEST 3L Series dead-locking cabinet lock takes a 7-pin housing so it can run on the same core system as the rest of the building.
4) Does the Lockey GM270 cabinet lock need batteries or wiring?
Neither. The GM270 Gemini is a mechanical combination lock, so there is no battery to change and no power to run to the cabinet. If you actually want the cabinet on access control or a release from a central point, that is a different product: the DynaLock 1410 Series and the SDC 290 Series are dual voltage electric cabinet locks, and the HES KS200 server cabinet lock integrates over Wiegand wired access control. Battery powered with a keypad and user codes is the SDC 295 Series, which holds 30 users.
5) What is a keyed alternative to the Lockey GM270 Gemini cabinet lock for a file cabinet where every user carries a key?
The Lockey GM270 Gemini is a mechanical combination cabinet lock with a 4-wheel code and an emergency key override on a 7-disc barrel, so routine access is by code and the key is a fallback. Where the facility wants key-only access instead, the Sargent 4142 is a horizontal cabinet lock with a 6-pin brass cylinder, and the Sargent 1655 is a 6-pin cabinet lock with field reversible handing. Both work off a cylinder and key for every opening rather than a dialed code, so access is controlled by key issue and the change process is rekeying rather than a code change.
6) How do I put cabinet drawers on the same key system as the rest of the building instead of using a combination lock?
The Lockey GM270 Gemini is a standalone mechanical combination lock, so it holds its own code and does not tie into a facility keying system. To pull cabinets onto an existing key system, the BEST 3L Series is a dead-locking cabinet lock with a 7-pin housing and vertical rim mounting, and the BEST 5L Series is a coin box cabinet lock with a 7-pin SFIC core housing. The interchangeable core housing lets the cabinet take the same core family used elsewhere in the facility. Sargent's KESO F1 4152 Series is a drawer cabinet lock built for security system integration, and the KESO F1 4252 Series is a drawer lock with field reversible operation.
7) What should I use instead of a mechanical combination cabinet lock if I need an audit trail or access control tie-in?
The Lockey GM270 Gemini is fully mechanical, so it needs no power or wiring and keeps no electronic record of who opened the cabinet. Where the cabinet has to report to a head-end, the HES KS200 is a server cabinet lock with Wiegand integrated wired access control, so it reads on the same credential infrastructure as the rest of the system. The SDC 290 Series is a micro cabinet electric bolt lock with dual voltage operation and the DynaLock 1410 Series is a dual voltage cabinet lock rated heavy duty, both of which are electrically released and require a power run to the cabinet.
8) What is the closest keypad equivalent to the Lockey GM270 if I want more than one user code?
The Lockey GM270 Gemini uses a 4-wheel mechanical combination giving 10,000 possible combinations, which is a single shared code that everyone with access dials. The SDC 295 Series is a battery powered programmable cabinet lock with a 30-user keypad, so each user can be issued a separate code and codes can be added or removed individually. The HES KP20 is a stand-alone keypad cabinet lock carrying a Grade 1 rating. The GM270 needs no batteries, while the SDC 295 is battery powered and needs a battery replacement schedule.
9) How is the Lockey GM270 Gemini fastened to the cabinet, and does it come with the screws?
It mounts with 2 x M4 pan head screws, which are what secure the lock to the cabinet face. Because it is a two-screw fixing rather than a nut-and-cam arrangement, the material behind the lock has to be sound enough to hold M4 threads.
10) Is the Lockey GM270 tough enough for a healthcare records room or a school storage cabinet?
It is built for commercial duty. The body is zinc alloy, which gives it corrosion resistance for daily-use cabinets, and the intended applications run to healthcare records storage, educational institution storage, government document storage, retail cash drawers, and industrial tool cabinets. For a server rack specifically, look at a purpose-built server cabinet lock instead, such as the HES KS-M mechanical server cabinet lock.
11) Can I standardize a whole bank of file cabinets on the Lockey GM270 Gemini and still tell them apart?
Yes, and that is where the 4-wheel system earns its place. Each lock is set independently out of 10,000 possible combinations, so a run of cabinets can carry one shared code for a department or a different code per cabinet, changed in place with the code change function. Finish is consistent across the fleet too: black, silver, and white are the three options, so you can match what is already on the other cabinets.
12) I want a keypad cabinet lock but not a mechanical one. What else is there besides the Lockey GM270?
The GM270 Gemini is the mechanical dial-wheel route, no power required. If you want an electronic keypad on the cabinet instead, the HES KP20 is a stand-alone keypad cabinet lock rated Grade 1, and the SDC 295 Series is battery powered with a programmable 30-user keypad. The tradeoff is straightforward: electronic gives you per-user codes and no wheels to spin, mechanical gives you nothing to power or replace.
13) Which cabinet lock handles left-hand and right-hand drawers, the Lockey GM270 or a Sargent cabinet lock?
The Lockey GM270 Gemini covers orientation by model: it is ordered with the keypad direction as left handed horizontal, right handed horizontal, or vertical, so the handing is decided at order time. The Sargent 1655 is a 6-pin cabinet lock with field reversible handing and the Sargent KESO F1 4252 Series is a drawer lock with field reversible operation, both of which are changed in the field rather than specified up front. For a mixed run of drawers where the installer will not know the orientation until the cabinet is open, a field reversible lock avoids sorting stock by hand.
14) Is the Lockey GM270 Gemini the right lock for a server rack or IT enclosure?
The Lockey GM270 Gemini is built for cabinet applications and can be flush fitted or surface mounted, in a body measuring 3 3/4 inch L x 1 5/16 inch W x 1 3/8 inch D. Locks made specifically for rack and server enclosures are a different family: the HES KS-M is a mechanical server cabinet lock rated Grade 1, and the HES KS200 is a server cabinet lock with Wiegand integrated wired access control. The KS-M keeps the no-power, mechanical operation of the GM270 while being purpose-built for server cabinets.
15) What looks like a substitute for the Lockey GM270 cabinet lock but will not drop into the same opening?
The DynaLock 1410 Series dual voltage cabinet lock and the SDC 290 Series micro cabinet electric bolt lock are both cabinet locks, but they are electrically operated on dual voltage, which means a power supply and a wire run to each cabinet plus a release device to unlock them. The Lockey GM270 Gemini is a mechanical combination lock in zinc alloy that is secured with 2 x M4 pan head screws and needs no power at all. Swapping a GM270 for either electric bolt lock is a wiring job, not a hardware swap.
16) Which cabinet locks carry a Grade 1 rating for a spec that requires it?
Of the cabinet locks in the comparable range, the HES KP20 stand-alone keypad cabinet lock, the HES KS-M mechanical server cabinet lock, and the HES KS200 Wiegand wired access control server cabinet lock are the ones stated as Grade 1. If a facility specification calls out Grade 1 on cabinet hardware, those three answer it directly, and the KS-M does so while remaining mechanical rather than powered.
17) What is the simplest lock for a cash drawer or coin box if a 4-wheel combination is more than the job needs?
The Lockey GM270 Gemini brings a 4-wheel code with 10,000 combinations, a code finding feature, and a code change function, which suits cabinets where the code is managed and rotated. Where a straightforward keyed drawer is all that is wanted, the BEST 5L Series is a coin box cabinet lock with a 7-pin SFIC core housing, and the Sargent 4142 is a horizontal cabinet lock with a 6-pin brass cylinder. Both operate on a key with no code to administer.
