Emergency Car Key Problems We Can Help With
Whatever your car key emergency, our mobile locksmiths are equipped to resolve it quickly and professionally.
Lost Car Keys
Lost your only car key? You don't necessarily need to have the original key available for us to make a replacement. Depending on the vehicle, we can cut and programme a new key using the information available from the vehicle. We'll confirm your vehicle details, check what type of key is required, and provide a clear quote before starting the work.
Keys Locked Inside Your Car
Locked your keys inside the car? We can help you regain access without unnecessarily damaging the vehicle. Our mobile locksmith comes to your location and uses appropriate vehicle-entry techniques to unlock the car. If the key is lost or damaged as well, we can discuss replacement options once you're back inside.
Snapped or Broken Car Key
A car key can become worn over time and eventually snap, particularly when turning the ignition or opening a stiff lock. If your key has snapped in the lock or ignition, we can assess the situation, extract the broken key where possible, and provide a replacement. If the key is still intact but damaged, we can also advise whether repair or replacement is the better option.
Dead or Faulty Key Fob
If your remote suddenly stops unlocking the car, the problem isn't always the key itself. A flat battery, damaged electronics, or a fault with the vehicle's key system can all cause similar symptoms. We'll check the key and vehicle before recommending a replacement. Where a replacement or programming is required, we can often complete this as part of the same mobile visit.
Stolen Car Keys
If your car keys have been stolen, replacing the key is only part of the solution. Depending on the vehicle, the missing key may also be able to be removed or deactivated from the vehicle's key system. We'll explain the available options for your vehicle so you can decide how you want to secure it after the theft.
Our Process
Car Key Cutting & Programming
A replacement car key needs to do more than physically fit the lock. Many modern vehicles use transponders, remote controls, or immobiliser systems that need to recognise the new key before the car will start.
Our mobile service allows us to handle the key cutting and programming at your location where the vehicle and key system allow it. After programming, we test the key with you to make sure the functions required for your vehicle are working correctly.
This can include standard keys, remote keys, transponder keys, key fobs, and smart or proximity keys, depending on the make and model.
