FAQs
Can you replace a lost Mercedes key without the original?
Yes. Our mobile technicians can create and program a new Mercedes key without the original. We use OBD2 diagnostics and, where required, EEPROM/ECU programming to pair your new key to the immobiliser. Proof of ownership is required before we start.
Do you offer non-destructive unlocking for Mercedes cars and vans?
Yes—wherever possible we use non-destructive entry techniques. In rare cases involving damaged locks or aftermarket shields, we’ll explain options first and proceed only with your approval.
How long does Mercedes key replacement take?
Many replacements are completed in a single visit. Timing depends on model, year, key type (smart/proximity vs remote blade), and whether all keys are lost. We’ll give an estimated timeframe when you call.
My Mercedes shows “No Key Detected.” What should I do?
Try a fresh key battery and hold the fob against the designated start area (refer to your handbook). If that fails, it could be an antenna, reader ring, or immobiliser sync issue. We can diagnose and resolve this on-site in Maidstone.
Can you program a spare smart key for my Mercedes?
Absolutely. We can supply and program a genuine-quality spare smart key, ensuring full functionality for lock/unlock and push-button start. Having a spare reduces future downtime and cost if a key is lost.
Do you cover Mercedes Sprinter and Vito vans?
Yes. We regularly assist commercial customers with Sprinter and Vito key replacement, programming, non-destructive unlocking, and ignition or door lock issues.
