Common Car Key Remote Problems


Car Key Remote Stopped Working?

 Did it completely stop working?  Or you just have to push the buttons really hard?  If it stopped working completely you may need to check the battery.  While this fixes the problem most of the time, sometimes the problem persists even after replacing the battery.  

Car Key Not Working Even After Changing The Battery

There are several things that can cause this to happen, a faulty ignition (not very common), faulty key or malfunctioning, car computer (very rare), and somehow the key became inoperable.  If the buttons are hard to push it could be from something sticky being spilled on the key or just lots of wear and use.  While some locksmiths may be willing to change the casing which might resolve the problem for a little while generally the problem is with the board of the key and will return and then you are paying for something twice versus once.  We recommend a new key at this point.
