Mercedes-Benz Key Programming FAQs

How long does Mercedes-Benz key programming take on-site?
Once our technician arrives at your vehicle in Croydon, programming a replacement or spare Mercedes-Benz key takes approximately 20–45 minutes using our OBD diagnostic tools.
Can you program a second-hand Mercedes-Benz key bought on eBay?
We strongly recommend against using second-hand smart keys because most Mercedes-Benz keys lock their transponder chip to the original vehicle VIN and cannot be recoded. We supply brand-new OEM-grade keys.
What happens to lost keys after you program a new Mercedes-Benz key?
We erase all lost or stolen key IDs from your Mercedes-Benz's immobiliser module memory so any missing keys can never be used to start your car again.
