It's inevitable that at any give time, you'll face some problems with your car keys. When this happens, don't fret. There are actually some things you can do other than calling a professional automotive locksmith.
Damaged Car Key
Actually, car keys are very durable. They wont bend or break easily. But on the other hand, nobody takes care of them. We throw them around as if they were useless objects. We let kids and pets play with them. And we use them daily (thats unavoidable). Eventually, the edges and grooves might get worn. The key wont fit with ease in the ignition or wont get inserted at all. The solution: naturally, you should take care of the key and always keep an extra one with you in case you need it.

Keyless Entry Remote Battery
Most car key remotes use category 4 button cell batteries that arent expensive. However, its still a good idea to verify the actual battery your remote uses and check to see whether or not its good. Once you know what type of battery is in your remote, you can either check the voltage with a multimeter, or just swap out a known good battery since they arent that expensive.
If your car key remote works after replacing the battery, then youre done. If it doesnt, then there could be another problem with the remote, like broken battery contacts or a problem with the buttons. Its also possible that your vehicle may have forgotten your fob, in which case you will need to reprogram it.

Worn Car Ignition Cylinder
Over time your ignition cylinder is going to wear down which in turn can wear down the wafers inside the tumbler of your car ignition. As this happens, your car key wont be able to press down the correct wafers and the ignition will not be able to turn over. In this situation one or few pins inside the cylinder is broken and the whole ignition needs to be replced.
