HIGH-END KEY CODING & ECU / TCU SOLUTIONS
for all vehicle brands.
GK Auto specialises in advanced key coding and control modules — ECU, TCU, BCM and immobilisers. If your vehicle doesn’t start, lost keys or has a security fault, this is the first place to call.
Keys, ECUs & TCU / BCM electronics
Before anything else, GK Auto is a specialist in electronic security and control units — your keys, ECUs, TCUs and BCMs. This is the heart of the business.
The keys, immobiliser, ECU, TCU and BCM must all agree before your car will start or operate correctly. When one part falls out of sync, you need someone who understands the security side, not just general mechanics.
GK Auto focuses on:
- Cutting and programming keys for a wide range of cars.
- Cloning and coding ECUs, TCUs and BCMs properly.
- Resetting or switching immobilisers off where appropriate.
- Keeping your vehicle secure while getting it running again.

Help from the workshop or at your location
Depending on the job, work can be done at 95 Charles Swart in Vereeniging or, where possible, at the client’s premises. This makes complex electronic issues easier to solve without unnecessary towing.
Ideal for ECU/TCU/BCM cloning, deeper diagnostics and bench work using specialised tools and equipment.
In suitable cases, keys and certain modules can be coded at your location so you can get moving faster.
Electronic expertise with real workshop experience
GK Auto blends hands–on automotive understanding with deep knowledge of the electronics that control modern vehicles. The result is smart, practical solutions.
Instead of trying to do everything, GK Auto is built specifically around key coding, ECUs, TCUs, BCMs and immobilisers.
Proper diagnostics and cloning reduce trial and error, preventing many unnecessary replacements and keeping costs realistic.
You’ll always understand what is wrong, what can be done and what the best approach is for your particular vehicle.
