How to remove a broken car key from a lock
If you are unfortunate enough to accidentally break a metal car key, it is likely to be in a door lock or in the vehicle's ignition switch. However, you may be able to remove the broken part without needing to
call us out to assist. If you have both pieces of a broken key, we can usually use these to cut a replacement for you. The following procedure
can also be used for broken keys in many normal types of domestic locks.
First, you will need a key removal tool similar to those in the image to the left. These can usually be purchased from locksmiths and some independent hardware stores, and are available from online retailers. However, unfortunately they are not normally
stocked by the larger DIY stores so it is worth purchasing a set at any time and keeping it in the toolbox 'just in case'.
Before starting to attempt to remove the broken part of the key, spray a small amount of a lubricant (such as WD-40) into the lock. This will not only make it easier to extract the broken part of the key, but will also wash away any dirt and metal particles. Next, ensure the lock is actually in the 'open' position - in other words, the position where you would normally be able to insert or remove the key. If the lock has been turned, it may be possible to return it to the open position using a flat-bladed screwdriver. Be careful not to use any excessive force. If the lock is jammed, then removal by this method will unfortunately not be possible.
If you look at the removal tool, you will see that it is a very thin strip of metal with a hook at the end. The trick is to insert the tool into the lock, sliding it down the side of the broken part of the key. With a slight twist, the hook should engage with one of the cuts in the key and you can gently pull it out.
If you have a spare, working key, then you can throw away the broken one. If it is the only key you have, then bring the pieces to us and we should be able to cut a replacement for you. Please note that in the interests of security you should attempt to further break the pieces before disposing of them. Do not throw them away together with each other, as someone else could potentially use them to have a key cut. If the key is a vehicle transponder type (with a remote unlocking button incorporated) then it should be destroyed forcefully, as it could still be used to gain access to the vehicle or used to programme another new remote.
If all else fails, then please contact us for assistance. We will be able to resolve the problem and provide you with working replacement keys or remotes. If you are local, we also offer an off-site service and can come out to you.
