Broken car key

If your car key has been broken or damaged, its metal part is no longer usable. The key chip must be removed and a new key be cut. If instead the key is simply worn out because you’ve had the car for a long time and you use it often, the key can be recut and restored for use. If the key is stuck in the car door and you can’t remove it, our locksmiths can diagnose the issue and use the appropriate tools to pull it out. If the key is stuck in the ignition, the locksmith will check whether this problem is key related or ignition related and find the appropriate solution. Forget car dealers, bureaucracy and wasting time. Get in your car.

Ignition Problems

When your ignition system fails the first thing that we look at is your car key. Over time car keys bear out from use. If determining that your car key is excessively worn, they can decode your current it and cut into a fresh key. If they think it still is not working, they disassemble your lock and replace the tumblers. If does not work even this then we think of replacing your ignition system.
