Though car key remote fobs are convenient to use, they stop working eventually. Fortunately, there are a few reasons that a keyless remote might stop working and most of them are easy to check yourself. However, if you broke your car key off in the lock, or if the car key is broken, the below points will not help you and you need to reach out an auto locksmith Arnold MO who specializes in handling broken key extractions. 

Damaged lock 

If the car key is not working when you unlock your car, there is a possibility that lock might have been damaged. Car door locks can wear down over time as you constantly use the key to unlock your car door. Since the door locks are on the exterior of the car, it can be damaged due to environmental changes and external force on the lock. The lock can be blocked by dirt and debris if it is not cleaned regularly. The locks can be damaged due to the external collision as well. 

Worn out key fob batteries 

Another reason why your car key is not working is the battery in your keyless entry remote is dead. Batteries need replaced after a period of time, and it is a common issue which you can fix easily. If you notice that your car is not responding to the commands and signals sent from your car keyless remote, it might be due to batteries. So replace with new batteries, and if they are still not working it could be a faulty key fob. 

The key fob is faulty 

If the issue is not with the battery, then it may be with fob itself. Contact a locksmith who handles key fob replacement in Arnold, and they can hook the fob up to a computer and ensure that the programming is good. If it is not working, the fob should be replaced. 

Damaged key 

This is one of the significant reasons why your car key is not working. The grooves in a car key respond to the internal mechanism of the lock. As keys are a physical component they are subject to wear and tear over time. Most car owners do not realize the effect that constant use might have on them. With poor maintenance, using them as a knife to open a box, and constant use, increases the probability of keys being damaged. If the groove on the key is altered and it is no longer able to operate the internal mechanism of the lock, it can be damaged and it is the reason why your car key is not working. 

This should help you determine why your car key is not working. However, it is advisable to reach out a professional locksmith Arnold MO to find out the cause and fix it.
