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!

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.

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!

Exceptionally happy with the service received with Lehane Autos today. Alex sorted out a problem many others could not get to the root of. He was very clear in his explanation and transparent with pricing. I can highly recommend this garage for anyone looking for a great honest mechanic.

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. Thankyou

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.

What Might You Need?

Locked Out or Lost Your Keys?

We assess replacement keys and vehicle-entry options for your exact vehicle and immobiliser system. Specialist non-destructive methods may be suitable, depending on the lock and condition. We explain any limitations, required parts and programming work before agreeing a quotation and a workshop or mobile appointment. See our Car Keys page for details.

We assess alarm, immobiliser and tracker options for your vehicle and requirements. Features, certification, subscriptions and monitoring depend on the exact product and package. Ask your insurer to confirm any required specification and acceptance before purchase. No system guarantees prevention or recovery of a stolen vehicle. StarLine installation is workshop-only.

Replacement components may require coding, programming, security authorisation or adaptation. We assess the exact part, vehicle and software before confirming whether we can help. Some used or incompatible components cannot be programmed, and physical installation or testing may require workshop access. Contact us before purchasing a part or booking the work.
