Mercedes GLS Locksmith Hamilton
The Mercedes-Benz GLS is the renamed successor to the GL-Class, Mercedes' full-size seven-seat SUV. The rename happened in 2016, close to the same point in Mercedes' lineup where the closed FBS4 key system replaced the older, independently-programmable FBS3 system — so as with the GLE, the badge on the back is a genuinely useful clue to what we can do.
- All-keys-lost recovery — no towing
- Smart key & transponder programming

- Dealer-level diagnostic equipment
- Fixed price quoted before we travel
“Lost the only key to my Hilux on a Friday afternoon. New key cut and programmed in my driveway by Saturday morning — and it cost half what the dealer quoted. Will absolutely call again.”
GL-Class (pre-2015, FBS3) vs GLS (2016 onward, FBS4)
GL-Class X166 (2012–2015): These run the older FBS3 immobiliser, which we handle in full — key programming, all-keys-lost recovery, and lost-key deletion, done at your vehicle.
GLS-badged X166 (2016 onward): From the 2016 rename, these run FBS4 — Mercedes' closed, server-authorised key system. No independent locksmith anywhere can legitimately write a key to an FBS4 GLS. We confirm by VIN before quoting rather than guessing from the badge alone.

Frequently asked
Mercedes-Benz key questions
Do you service the Mercedes GL-Class?
Yes — pre-2015 GL-Class vehicles run FBS3, which we program in full.
Do you service the Mercedes GLS?
GLS-badged vehicles (2016 onward) run FBS4, which is dealer-only. Call with your VIN and we will confirm, but in almost every case a GLS needs Mercedes themselves.
How much does GL-Class key replacement cost?
Roughly $450–$700 for a standard key or remote on these larger-platform Mercedes, more for all-keys-lost. Confirmed once we have your VIN.
