Lost or Broken Car Key Fob? We'll Replace It Today

Our Core Key Fob Services

1. Car Key Fob Replacement

Whether your fob is completely lost, irreparably water-damaged, or the circuit board has failed, we provide full car key fob replacement on the spot. We decode your vehicle's locks with specialist non-destructive tools to cut the physical emergency blade, and supply a brand-new fob casing and internal board that matches your vehicle's exact specifications.

2. Remote Key Programming

A new key won't start your car unless it communicates securely with your vehicle's internal computer. We provide expert remote key programming using the exact same software systems as the main dealers. We ensure the transponder chip and unique rolling codes are perfectly synced to your car's immobiliser and Body Control Module (BCM), ensuring seamless push-to-start or remote locking functionality.

3. Spare and Duplicate Key Fobs

Relying on a single car key is a massive risk. If it breaks or gets lost, you are left stranded. We can quickly cut and program spare and duplicate key fobs at a fraction of the dealership price. Having a duplicate made now is a fast, affordable process that saves you from the stress and high cost of an "all keys lost" emergency callout in the future.

4. Fob Repairs & Battery Swaps

Sometimes a full replacement isn't necessary. If your fob is unresponsive or the rubber buttons have worn out, our technicians can diagnose the fault. We can resolder broken micro-switches, replace dead CR batteries, and swap out cracked outer casings to make your existing key work like brand new.

The Smart Alternative to the Main Dealer

If you've lost your smart key or your fob has stopped working, your first instinct might be to call the main dealership. Here is what usually happens: you are quoted upwards of £300, told you need to pay to tow your car to their garage, and informed you’ll have to wait 1 to 2 weeks for a new key to be ordered from overseas.

At Royale Car Keys, we do it differently.

We carry high-end, dealer-level diagnostic equipment in our vans. We handle the entire process at the roadside. If your keys are lost or stolen, we will access your vehicle's OBD port to delete the old keys from the engine control unit (ECU), ensuring they can never be used to steal your car, before providing a brand-new, fully functioning fob right there on your driveway.

Why Trust Royale Car Keys?
