Electronic Steering Lock Repairs for Mercedes

The electronic steering lock (ESL) is a security feature that is designed to prevent your vehicle from being stolen. However, if it malfunctions, this will prevent you from driving your car and make it completely inoperable. It’s important, therefore, to recognise the symptoms and know what to do should they occur.

ESL issues are common in many Mercedes models as well as Volkswagens and some other European brands. At Northside Car Keys, we are fully familiar with the problem and have the knowledge and equipment to carry out Mercedes ESL repairs quickly and effectively so you’re back on the road with a minimum of delay.

When Mercedes ESL Replacement or Repair is Necessary

Electronic steering lock repairs for Mercedes are generally necessary when any of the following issues occur:

  • The key will not turn in the ignition. This will sometimes happen only occasionally, typically when the weather becomes colder, but can become more frequent as the situation gets worse.
  • The key will turn but the engine doesn’t start. In these instances, there may also be no dashboard lights showing.
  • The steering lock isn’t released when the key is turned or may not be activated when the key is removed from the ignition.
  • Diagnosis fault codes A25464, A25407, A25408, A25409 and A225408 will indicate problems with the ESL.

Mercedes cars with an ESL require a signal from it to allow the engine to be started. If this signal isn’t received, then other computers will, for safety reasons, prevent the car being started. The problem is often caused by a small DC motor that winds the lock peg in and out of the splined steering column. This motor will wear over time and eventually fail so that the listed problems occur.

If the faults are intermittent, it’s important you deal with them quickly. If not, they will get worse and eventually lead to failure of the ESL so that the car becomes inoperable and more costly to repair. Read More

Thanks so much Jon for your reliable service. I was beyond stressed losing both my keys; I thought I was going to be in a world of pain dealing with the Hyundai dealership - not to mention the price they had quoted me. 10/10 service provided and I will happily recommend you to friends and family, an absolute pleasure to deal with

Jon has given an excellent service , within 10 minutes he fixed the issue and he has the right skills and tool to diagnose the issue and fix it.


I had bought a VS ute and due to a series of unfortunate events found myself locked out. Called Jon and he was super nice and professional also very prompt. He easily supplied me with a brand new key and delivered it to me with no fuss at all. Would definately recommend this company to anyone and will use them next time.
Its so refreshing to find good old fashioned service in a rush rush world. 10/10 A+++

Chris, Redcliff

Northsidecarkeys were the best value quote I could find, one of the other companies actually warned that for that price they might not know what they are doing, but the keys were perfectly fine. They even delivered the key on the weekend to my car. They made the painful ordeal of losing modern car keys a bit less painful.

Anonymous, Ascot

Thanks Jon, for a quick response and excellent service. We’ve been meaning to get a second key for our car for some time and it couldn’t have been any easier. And service with a smile!

Literally the best car lock smith ever, i have had many auto locksmiths come to cut and program a key for my VW gti, but they all failed, northside car keys were not only $100 cheaper, but really professional as well. He did not quit at the challange and did the extra work for free to make it work. Thank you very much, would recommend him to anyone and everyone.


My daughter lost her car key unable to get home and go to work when I contacted Northside car keys I was impressed with the courteous friendly professional customer service by Jon. With an already packed day he was able to alleviate my stress and get my daughter back on the road. I would highly recommend this company to everyone. Thanks very much Jon!
