We handle every major make and model, from traditional cut keys to the latest push-button and proximity systems. As the only RAA automotive locksmith contractor in South Australia, our service standards are unmatched.
Car Key Cutting & Replacement
Lost, broken, or stolen car keys? We cut and supply replacement keys for all makes and models — from traditional cut keys to modern laser-cut and proximity/smart keys. Our equipment handles even the latest vehicles.
Mobile Lockout Service
Locked out of your vehicle? Our mobile team will come to you — at home, work, a car park, or on the roadside. We operate a fleet of six service vans across Adelaide for fast response times.
Transponder Key Programming
Modern vehicles use transponder chips that must be coded to your car's ECU. We program transponder keys for all major makes using professional diagnostic equipment — at a fraction of dealership cost.
ECU Recoding
When all keys are lost or a security module replaced, the vehicle ECU often needs to be recoded. Our technicians use specialist automotive diagnostic equipment to restore full security system functionality.
Lock & Barrel Repairs
Worn, damaged, or stuck door locks and ignition barrels repaired or replaced. We service all vehicle lock components including door locks, boot locks, ignition locks, and glovebox locks.
Door Lock Recoding
Bought a second-hand car with missing keys? We can recode the door locks and ignition to work with a new set of keys, restoring full security without replacing the barrel assembly.
