Vehicle electronics are the foundation of what we do at Lehane Autos. With deep expertise in specialist electronics and car retrofits in Swansea, we work far beyond basic diagnostics, repairing, extracting, recalibrating, reprogramming, and retrofitting vehicle control systems using the correct procedures and manufacturer-level tools.
Whether you need a direct electronic replacement, advanced coding, or a complex car retrofit, our experienced technicians deliver precise, reliable solutions for both private owners and the motor trade.
At Lehane Autos, our understanding of vehicle electronics goes far beyond the miles of wiring inside modern vehicles. We specialise in the data stored within control units, how that data is transmitted, interpreted, protected, and – when required – securely extracted or modified.
This deeper understanding allows us to solve problems that many garages and mechanics in Swansea struggle.

Yes. We have many different methods of extracting data, and if missing, in most cases we can build new data from other component data to match the immobiliser.
Very much vehicle and spec dependent. In some cases with vehicles it is possible when all hardware is present but the coding is set to prevent operation. But in most cases, additional parts are required. Some more than others, some require missing wiring also. Please contact us with full vehicle info and include images to help us assess. In some cases we might need to plug into the vehicle with a diagnostic tool, to get component part numbers to assess vehicle spec and component compatibility. This is subject to charges.
Yes, To most ECUs we’ve spent many hours and time testing solutions across many brands. With much success of having engines running with out an immobiliser key.
Yes we can. But, without knowing the vehicles immobiliser data. we would be guessing correct data. So we would need a known working, paired immobiliser data component sent with the component to be programmed. Then we can extract needed data. this is subject to availability, type, age, make and model.
Yes. We assist garages, dealerships, fleet operators, individuals locally and worldwide. In person, remote desktop assistance and by postal.

I can't recommend Lehane Autos highly enough - we had a number of fiddly electrical jobs that needed doing on our VW T6, including providing & mapping a 2nd key and Alex sorted them all out perfectly, for a fraction of what it would have cost at a VW main dealer. Also a great guy to work with and we've already recommended him to a number of our VW friends. Lehane Autos is now our go-to for any future electrical work. Can't fault him!Posted on Google![]()

My car was off the road for 6 years during which time I had lost the keys. I had the car transported to a Nissan dealership, their assessment was a new engine wiring loom was required before a new key could be reprogrammed! I proceeded to contact other car garages, unfortunately none offered promising advice, then a friend recommended Lehane. Alex visited me, removed the BCM and ECU then took them back to Lehane's premises for reprogramming to a new genuine Nissan key which they obtained. Alex returned to reinstall the components, after which the car started first time and I was able to drive it. Alex was friendly, polite and I had complete confidence in his ability. The cost of the repair and callouts were not high, worth every penny! I am very satisfied and highly recommend Lehane Autos.Posted on Google![]()

Couldn’t get my s2000 started for weeks. Took it to Lehane Autos and he’s managed to diagnose it and rectify the issue and get me back on the road in time for a car show. Really nice guy, really fair price. Definitely recommend & going back for more work really soon. Thanks so much!Posted on Google![]()

I’ve had Lehane Auto do alot of work on the electrics from my 2010 Volvo xc60. ECM and srs module both decided to give up at the same time . Spoke to Lehane about both problems and a solution was found. Took the car there and within a matter of hours both issues were rectified and the vehicle was driving amazing once again. 0 hassle, 0 time wasted. Incredibly efficient and a very good price. Truly a happy customer. Will be back in the future for other work on other vehicles . Very friendly and professional , would recommend to anyone needing any type of vehicle work. ThankyouPosted on Google![]()

Took my wife's Range Rover in with audio issues, Lehane were able to drill down to the specific issue so I could fix it, and found the cause of another, unrelated issue also allowing me to get that sorted alongside. Great communication, helpful and friendly chap. Highly recommended.Posted on Google![]()
