About Your 2026 Mercedes-Benz GLE
Mercedes-Benz is one of the most complex mainstream brands in the industry — the only one we treat as a separate routing on the website. The reason is the FBS3-to-FBS4 transition that happened around 2014. FBS3 vehicles (pre-2014) are fully serviceable on-site at significant savings vs the dealer. FBS4 vehicles (2014+) require dealer-level encryption infrastructure for new key programming; we can assist with diagnostics, key shell replacement, and selected procedures, but a brand-new key for an FBS4 car is realistically a dealer job. The good news: most FBS4 'won't start' cases are actually battery / fob sync issues, not requiring a new key. Always call us first before driving to the dealer.
GLE (formerly M-Class) — pre-2014 ML W164/W166 is FBS3, 2014+ GLE W166/V167 is FBS4.
2018-and-newer Mercedes use FBS4 second-revision (CLS, AMG GT, EQS, etc.). Same restrictions as 2014–2018.
SUVs and crossovers tend to have the proximity Smart Key on higher trims and a basic transponder key on the base trim — we always confirm the exact fob part number before arriving.

Frequently asked questions
Can you make a key for my 2014+ Mercedes?+
For new key programming on 2014+ FBS4 vehicles, the dealer is required. We can assist with battery replacement, fob sync, shell swap, and diagnostics on-site — and most 'won't start' cases are actually sync issues, not requiring a new key.
What's the difference between FBS3 and FBS4?+
FBS3 (pre-2014) uses an encryption that's been broken by aftermarket programmers — that's why we can service it on-site. FBS4 (2014+) uses a new encryption layer that requires dealer-level infrastructure to write new keys.
How much does a pre-2014 Mercedes key cost?+
Pre-2014 Mercedes spare keys typically run $295–$495 cut and programmed on-site, depending on model. Compare to dealer pricing of $500–$1,200.
