The Interlock Assurance
More Than Just Buying a Digital Lock
We help make sure the lock is suitable for your entrance, properly installed, and supported after installation.
No-Fit, No-Fee Before Installation
We check compatibility before installation. If the planned lock cannot be properly installed onsite and we cannot provide a suitable compatible alternative, you will not be charged for the unsuccessful installation.
30-Day Workmanship Guarantee After Installation
If an issue is confirmed to have been caused by our installation workmanship within 30 days, we will return and rectify the workmanship issue without an additional workmanship charge.
Replacing an old Gateman digital lock
Many condo and HDB units still have the Gateman lock fitted years ago. When it starts failing, you can replace it like-for-like or upgrade to Interlock Mercury. Either way, our own installers fit it, usually within the same week.
Signs it's time to replace
- Won't auto-lock when the door closes
- Card or tag not reading
- Keypad or fingerprint not responding
- Won't unlock, or jams often
- Loose handle or a display that stays dark
- Battery leak or rust in the battery case
Some faults can be repaired. See repair or replace for how we decide.
Like-for-like replacement
Prefer to stay with Gateman? The Gateman SP122 is the usual replacement for older Gateman locks in condos and HDB flats.
We recommend the model closest to your current lock, based on your door.
Upgrade to Interlock Mercury
Every Mercury lock can replace a Gateman mortise lock. We drill new holes for the Mercury, but its larger body covers the old cut-out completely, so there's no patching.
- Bigger mortise with more locking bolts
- An extra double-lock bolt
- Stainless steel mortise: more rust resistant and harder to break
Popular picks: Mercury X6 (face recognition), X2 and X5. Rim (add-on) locks are case by case, so send us a photo first.
Installation is included in the lock price. We aim to install within the same week.
