Send us your engine ecu, immobiliser box and one key.

TEL: 01373 302412

After three years of R&D in house we have made a solution to free run this engine ECU. The car will start with any key, there are no signs visible displaying in cluster or by diagnosis.  All your remote keys will continue in the normal manner. This service is made uniquely for the original vehicle ECU, all coding and VIN remain original.  The immobiliser box remains in the car with all connectors attached.

This service offers a solution when the 1708201726 5WK48697 Siemens Immobiliser box will no longer allow the correct engine start status.  Start error shows in the cluster and the engine fails to crank.  In this situation if the engine ECU can not be re-personalized after resetting, a new OEM precoded Immobiliser box will be required to keep the remote keys functional and car free of other gremlins.

This service is uniquely produced for your ECU, subject to work load three days may be required to carry out this process. This is our own solution, all work is carried out in our office. All our normal solutions apply to this engine ECU contact us if you require another service.

We require your engine ecu, immobiliser box and key with your contact details.

    Mercedes SLK

    Posted by Peter Western on 14th Nov 2019

    I contacted this company as they were the only people saying they could bypass the immobiliser on my SLK. I have to say I was skeptical when they said it was a new service, but I had nothing to lose as nobody else could do it. I sent the parts, expecting to hear in a few weeks but the next day they phoned to say it was done and ready to be returned. I have to say I had everything crossed when it came to turning the key, but it worked. Brill, brill, brill, this car had been parked up for 9 months and I was on the verge of giving up with it. Definitely recommend this service ******** Station Garage
