Remote Key Repairs

 Electronic repair for a remote control car key (key fob) typically targets common failure points on the printed circuit board (PCB), such as worn tactile micro-switches, loose battery contacts, or cold solder joints. 


If possible we can repair your key at the fraction of the cost of a new key

Car Key Programming

 Electronic car key programming connects a replacement key fob or transponder chip to a vehicle's onboard immobiliser system, authorising the new key to start the engine and operate the central locking. read security access codes, and register the new key's unique transponder frequency.  

Key Cutting

Key Fob Refurbishment

 Electronic car key cutting involves precision-milling a physical metal key blade or emergency insert to fit a vehicle's mechanical lock cylinders. Modern automotive keys—such as laser-cut, are duplicated using specialised computer-controlled key-cutting machines. These automated cutters read the unique key code profile via optical laser scanning or direct code entry, milling the precise grooves into a blank key

Refurbishing your existing car key fob is a fraction of the cost of buying a complete replacement from a dealership, saving you up to 70% while keeping your original equipment. Most "broken" keys suffer only from cracked outer shells, worn-out rubber pads, or dead batteries, while the internal microchip, immobiliser transponder, and circuit board remain fully functional. By transferring your original electronic components into a fresh, high-quality aftermarket shell and transferring or re cutting the blade, you get a fully restored key

 Car transponder chip cloning and programming are two distinct methods for pairing an immobiliser chip to a vehicle. Cloning involves using a dedicated key programmer to read the unique digital signature from an existing, functional key and copy its exact data directly onto a blank, rewritable chip  

Diagnostic Service

 Car diagnostic is an essential steps for  immobiliser programming we scan the vehicle's Engine Control Unit (ECU) and Immobiliser Control Module to detect diagnostic trouble codes (DTCs) that might indicate faulty antenna coils, or key authorisation errors. Concurrently, reading the live data stream reveals the registered key count—the total number of transponder keys currently paired to the car's memory. Checking this count ensures that lost or stolen keys can be wiped from the system before programming new keys 

RFID Tags & Cards Cloning

  Cloning an RFID card or tag means copying its unique ID or data using a special reader, and then writing that exact information onto a blank, writeable card. Once copied, the new card acts as an exact duplicate, allowing it to open doors or pass security systems just like the original.

 Speed limiters on certain commercial vans can be removed or adjusted through electronic control unit (ECU) reprogramming. This modification allows the vehicle to bypass factory-set speed caps, giving the engine full access to its intended performance capabilities. 

Dash Cam Fitting

Dash Cam Fitting

 Fitting a dash cam provides invaluable peace of mind by acting as an impartial eyewitness on the road. In the event of an accident, insurance fraud, or disputed liability, high-definition video footage offers concrete proof of what really happened, protecting you from unfair blame and potentially lowering your insurance premiums. Additionally, many modern dash cams offer parking surveillance, safeguarding your vehicle against hit-and-runs or vandalism even while you are away.
