One thing virtually all car owners have experienced is their car keys refusing to work. Imagine you are rushing out to work and you are unable to unlock your car or start it. You check what the problem is only to realize that your car key has stopped working. While you are locked out of your car trying to figure out what the cause of the problem is, you should also be thinking of the auto locksmith Belfast that you can call.

First off, if your car key is broken or if it breaks inside the lock, these reasons do not apply to you. Your problem is different, and you should reach out to an auto locksmith Belfast to check it out for you.

Is your lock damaged?

If, when you try to unlock your car, the car refuses to open, the problem might be with your car lock. If your car is a fairly recent model, you probably will never have this kind of issue as most new cars come with keyless entry remotes and key fobs. But if your car is an older model that requires opening the door with the key, this issue is quite possible. The lock gets spoilt over time after constant use, and in this case, the internal mechanism of your car lock may have worn down. Sometimes, it may be dirt or dust clogging up the lock, and all you have to do is clean the lock. In more extreme cases, an external collision could damage your car lock as well. The bottom line is if your car refuses to open, try and figure out whether the problem is with your lock.

Is your key damaged?

If your car lock is not damaged, it is possible the key is damaged. A damaged key does not necessarily have to be a key that is broken into pieces. Your car key has grooves embedded on it which must correspond with the internal mechanism of your car lock or the ignition. If these grooves or any other element on the key have gone through some wear and tear, that key will not work. So, you need to pay attention to your key and if you do not know what to look for, an auto locksmith Belfast can take a look at your keys and give you a report on its current state.

Damaged Ignition Cylinder

The way it is possible for the internal mechanism of your car lock to be damaged, it is also possible for the internal mechanism or cylinder of the car ignition to be faulty if the car refuses to start. Get an auto locksmith Belfast to check it out for you as this is not something you can check by yourself.

Are your key fob batteries worn out?

If you drive a modern car that uses a Key fob or keyless entry remote, it is possible your key batteries have run out of juice. It is normal for batteries to run out after a certain period of use. This is a common issue, and it has a simple solution. Find new batteries and replace the old batteries with the new ones. You should be good to go afterward.

Is your Key Fob or Keyless Entry Remote Damaged Internally?

After replacing the batteries, if your keyless entry remote still does not unlock your car, then you have a much serious problem on your hands. The key fob works on the principle of communication between a transmitter and receiver. If any or both of these components are damaged, the car key will not work. The damage could be caused by frayed wires, dropping the key or even moisture. You need to have the key fob checked so you can ascertain what exactly is the problem with it. 

Is the key programmed?

This is another issue that may prevent you from being able to unlock your car. Usually, there is no need to pair traditional keys, but for transponder keys and keyless entry remotes, they have to be paired with the car for them to work. This hardly happens with keys that come with the car originally; it is more common with people who get duplicate car keys or replace their car key remotes. The new key has to be programmed to work with your car, and this fact is one that most people forget. An auto locksmith Belfast can do this.

Did you get aftermarket car keys?

When people are looking to replace their car keys, they go for cheaper options known as aftermarket car keys. Aftermarket car keys are usually not designed for your specific car model and brand, or they may not be fully programmed to work for your car. So, you may need to do some additional work on the key so it can be paired with your vehicle. If you buy an aftermarket key, do make sure all the programming and pairing work is done on it to avoid any future headaches.


Your car is useless without its key and if your car key refuses to work on a particular day, your activities for that day may be hampered. The points above are the most common reasons why your car key may not be working to either unlock or start your car. So, take your time to digest them keep them in mind and should you ever find yourself in such a situation, you would be able to do the necessary checks on your car’s components. And of course, to solve any car keys or lock problem in Belfast, you should not hesitate to get in touch with an auto locksmith Belfast to check it out for you instead of tampering with things and potentially causing further damage.
