Mechanical combination gate locks

Which code lock suits the way you use your gate?

Which is the best combination lock for my gate?

For a metal swing gate, we recommend starting with Gatemaster's Superlock 2.0. The BDGS and BDG models need no power, have adjustable latchbolts, latch when the gate closes and carry a five-year manufacturer's warranty. Choose BDGS if people should leave with a handle, BDG if they should enter a code on the way out, or BQDG if a push pad is preferable. The lock catches a gate that has closed; add a gate closer if the gate must also pull itself shut. For a timber or composite gate, start with the surface-fixed models instead.

Will you need to change the code often?

If several people share the gate and codes change regularly, consider single-sided RapidReset BDGSRR or double-sided RapidReset BDGRR. RapidReset lets you change the code at the keypad without removing the lock. Standard BDGS and BDG are different models, so choose the RapidReset version if that feature matters to you.

Will the lock fit your gate?

For a metal-frame Superlock, measure the width of the frame section where it will bolt on and the gap between the closed gate and post. The Superlock 2.0 packs are offered for 10–30 mm or 40–60 mm frame sections, with parts sized for the chosen width. Note which side the lock will sit on and whether the gate opens inwards or outwards, and confirm where the latch will meet the keep. If you have an existing gate, send us photos and those measurements and we can help identify the right version.

For a timber or composite gate, choose a surface-fixed model and use its own gate-thickness and fixing instructions. A similar-looking metal-frame bolt-on lock is not a substitute.

Which code lock suits an exposed or coastal gate?

For a timber or composite gate in a tougher outdoor position, consider the Borg BL2605 ECP. It has a marine-grade finish, a rim deadbolt and on-the-gate code changing, and is offered for gates or doors 60–80 mm thick. The similar-looking BL2005 is not the choice for an exposed gate. For any other model, tell us if the entrance is fully exposed or coastal so we can match the lock to the site rather than treating every keypad as equally weather resistant.

Do you need a backup key?

A mechanical keypad does not automatically include a key override. If a separate key must open the gate when the code is unavailable, tell us before ordering and we will confirm a model with that function. Do not assume a key cylinder is included with the BDGS, BDG, BQDG or BL2605 choices above.

Already have a code lock?

Send us the reference, a photograph of each side of the gate and the receiving keep. We can help you find the same model or the closest suitable replacement, including a matching keep or shroud if that is all you need. If the gate slides sideways, see our sliding-gate locks for a hook and receiver made for that movement. If you need a separate lock around a bar or bolt instead, compare padlocks and padbars.
