Mr Jubel
Excellent customer service
Very pleased with the service. I arrived early but they were able to start work immediately and finished the job quickly. The full functionality of the new key was demonstrated (each button, the keyless aspect, the physical key aspect) so I left fully confident that a good job had been done. The price quoted was better than I was offered at my normal dealership. All in all, highly recommended!

Would have been a 5 if my emails had not gone into your spam and meant I did not get a reply for 5 days. Easy for you to sort out. Otherwise all very good, quote was clear, appointment quick and arrived on time and did good job.
Mr Mike Cox
My car is an Infiniti imported from Dubai and the main U.K. dealer was unable to programme a second key. The radio frequency used on an import is different from a domestic supplied car. Car key Solutions were able to source a key and programme to my car in a couple of days. the engineer did the job in half an hour and took me through everything to make sure the key worked correctly. I can thoroughly recommend Car Key Solutions.

Our responsive mobile Mercedes key replacement service will come to you, where you are, as quickly as possible, seven days a week.

How Much Do You Know About Mercedes Car Keys?

Mercedes is one of the very few manufacturers who have used a tiny variation of keys over the years. From early 2000, the plastic Mercedes remote key used proved popular used across all range of Mercedes vehicles. Later, this has been updated to a more stylish chrome finish version.

From the mid-1990s Mercedes keys integrated the immobiliser function and the flip-out remote key. This way, only a key programmed to a specific vehicle can enable engine start.

Mercedes have integrated electronic ignition switches known as EIS – an electronic unit that holds the data of keys programmed. Another anti-theft device introduced was electric steering column locks known as ESL on most of their models.

Drivers will think of their closest dealership as their first option when in need of a Mercedes key replacement. To have a new Mercedes key from a dealer means paying for the car to be towed there. Sometimes this has to be twice, once when the order is placed then again once when key arrives and needs initialising. At a dealership, you will need to present several documents to order the replacement key and have to wait up to 10 working days.

Car Keys Solutions can supply Mercedes car keys on the spot, including ESL replacement mobile and EIS repair and programming – most of the time, on the same day. Our services are mobile with minimum inconvenience and at a fraction of the cost compared to main dealerships.

It is impossible to clone or override keyless Mercedes Keys. The immobiliser chip is encrypted with a sophisticated coding system that can only be read and programmed with the latest diagnostic equipment.


Mercedes models from the mid 1990s use the remote signal to operate central locking and disable the immobiliser system. Those keys have no transponder chip. 

Most Mercedes keys used later work slightly different to other car keys when it comes to the immobiliser system. They send an infrared signal to the electronic ignition switch, that upon recognising the message, enables engine start.

Car Keys Solutions provides you with roadside car key replacement and offers a service suitable for all Mercedes vehicles that are on the road – whether it’s a car or van. There are several problems that you may come across when it comes to Mercedes vehicles including keys locked inside, faulty keys, defective steering column lock, key duplications or even electronic ignition switch failure. No matter where you are, our Mercedes specialists can come to you in an emergency, or at a time that suits you by appointment.


We cover most Mercedes-Benz models for key fob replacement, ESL repair and EIS repair or replacement.

Lost or Broken Key Replacement

If you have lost or broken your Mercedes keys and you need a replacement, then we can provide you with a brand new set of keys while you wait. You don’t have to worry about the expense of towing your car to a dealer or having to wait ten working days. We will come to you wherever your vehicle is.

Mercedes Spare Keys

If you have bought your car second hand, you may only have been given one car key to start the engine. If you need a Mercedes spare key, we can carry out a quick car key duplication service for you on a same day service. It’s always advised to have a spare Mercedes key, in case one of them gets broken or lost in the future. Creating a spare key by using an auto locksmith when there is one operating could significantly save you on a new Mercedes key cost. It is always easier to create a replacement key when there is one available, compared to having a new one made when all keys are lost.

Mercedes Key Programming

If you have a Mercedes model that was manufactured after 1995, then it is likely that your Mercedes keys will have a transponder chip. Sometimes, those key chips may stop operating and will need expert, diagnostic equipment to work again. If it is beyond repair, we can program a new Mercedes key on the spot.

An incorrectly programmed Mercedes key will prevent the engine from starting.

Mercedes Unlocking

Locked out from your Mercedes? Have you locked your keys inside your car or in the back of your Mercedes van and need instant access? 

It happens more than you think. We can provide you with a Mercedes locksmith who can unlock your car and retrieve them. They will leave your vehicle in pristine condition.

Mercedes Key Repair

If your Mercedes key has cracked or chipped, has stopped operating or is just too worn, you may need it to be repaired, rather than replaced. Our Mercedes auto locksmiths can repair Mercedes keys on on-site with a same day service available.

Mercedes Ignition Switch Repair

Like any other electronic component, Mercedes electronic ignition switches can stop working. You may find yourself having problems with your Mercedes ignition switch, which has gone faulty and may need fixing. Our technicians use the latest equipment for the testing and repair of electronic ignition switches. The cost is lower than if you went to a main dealer, and again with no delay, so you can resume your daily life without being left for several days without your Mercedes. 

Electronic Steering Column Lock Repair

Steering column lock failure is becoming a common reason for not being able to start your Mercedes E Class, C Class Mercedes Sprinter or Vito. Here at Car Keys Solutions, we specialise in Mercedes steering lock repairs and can provide you with a quick diagnostic on your Mercedes non-start issue. We offer Mercedes replacement steering column locks on  a same day service, and mobile service at your location to get you back on the road as soon as possible. Find out more about mercedes steering lock symptoms and repair on our dedicated page.

Electronic Ignition Switch Replacement

Unfortunately, as we have seen many times, Mercedes Sprinter ignition switches are stolen. 

Here at Car Keys Solutions, we have a solution for these situations as well. 

We can offer same day Mercedes ignition switch replacement and additional protection solutions. Contact us about what your vehicle requires, and we’ll be happy to assist you.
