Frequently Asked Questions
Mercedes all keys lost — kerbside?+
Yes for pre-2015 FBS3. W204, W212, W221, W164, W251, W639 Vito and W906 Sprinter (roughly 2005-2014) are handled mobile with dealer-grade AKL kit. No tow. Post-2014 FBS4 (most 2015+ Mercedes) is dealer-only — we don't take those jobs.
How long does a Mercedes AKL take?+
Pre-2015 FBS3 typically 90-120 minutes. Fixed price agreed before we attend.
Will the lost key still work afterwards?+
No — the AKL procedure invalidates every previously-paired key (TPRoll/SK count incremented). Found keys will no longer start the car.
How much is a Mercedes AKL?+
From £395 for pre-2015 FBS3. Always typically well below Mercedes main dealer, plus saves the recovery tow. Post-2014 FBS4 is dealer-only.
AMG, G-Wagen, Sprinter — covered?+
Pre-2015 FBS3 AMG (W204 C63, W212 E63, W221 S63), G-Class W463, V-Class W639, Vito W639 and Sprinter NCV3/W906 are supported. Post-2014 FBS4 (W463A G-Class, W447 V-Class/Vito, W907 Sprinter VS30, current AMG, EQ) is dealer-only.
