Not every Mercedes key is the same job. The range spans simple metal-blade keys on older models to encrypted smart keys and push-to-start systems on current S-Class and AMG vehicles, and each one calls for different equipment to cut and programme correctly. Getting a like-for-like replacement, rather than a generic key that merely fits the lock, usually means working with someone who has dealt with your specific Mercedes generation before.

Mercedes key replacement prices can vary depending on several key factors, including the model, year, and key type. Many modern Mercedes vehicles use smart keys, keyless entry, or push-to-start systems that require advanced tools and dealer-level programming.
Whether you require emergency assistance or can schedule a service in advance will also affect the overall cost. Generally, replacing a lost key is more expensive than duplicating a working one.

THE REASON AM WRITING THIS REVIEW.
The FOB or Remote Key for my Sprinter Van was completely broken. I had to park the van, doors unlocked, on a difficult estate. Contacted my Big Motoring Organization, a waste of time. By accident when searching for the meaning FOB on AI, I read that I could get a FOB Key from TIMPSONS of whom I have never heard before.
Timpson said they could only do it the next day, but kindly suggested that I search the web for Auto locksmith. Within about two and a half hours of contacting ukcarlocksmith.co.uk, they arrived at my door, programmed a brand-new Mercedes Approved Remote Key or FOB for me. Faster and Cheaper than trekking to main dealership. So impressed that I will pass on this company’s name to everyone I know.
Very impressive – I lost my car keys in the plane
I lost my car keys in the plane. After battling with ‘my’ car rescue company for 14 hours to get my partner, me and our car taken back home (they agreed to do it of course as I paid for Nationale recovery but ‘none of the agents wanted to drive that far’ (41 miles) they said. I finally called UK Auto Locksmith who said they would come to the mid-stay parking of stansted airport, where our Mercedes was parked and make a new key on the spot. Cost £200. I have insurance, so I agreed. Angelo arrived and 30 or 40 min later, gave me a brand new Mercedes key. Our car started spot on. Done. Excellent service, very professional. Highly recommended.
