Have you ever gone to unlock your car door only to find that your key won’t work? It’s a frustrating experience, especially if you’re in a hurry. But before you call a locksmith, there are a few things you can check. Here are some of the most common reasons why your car key is not working, from a locksmith’s perspective.
1. Dead batteries
One of the most common reasons why your car key is not working is because the batteries are dead. Most car keys have built-in batteries that power the remote unlocking feature. Over time, these batteries will die and need to be replaced. If you find that your key fob isn’t working as well as it used to, it’s probably time to replace the batteries.
2. Worn-out keys
Just like with any other type of key, car keys can become worn out with time and use. The teeth on the key can become damaged or bent, making it difficult to insert into the lock. In some cases, you may be able to have a locksmith cut a new key from the old one. However, if the damage is too severe, you may need to get a new key from the dealership.
3. Dirty or corroded locks
If your lock is dirty or corroded, it can prevent your key from being able to turn it. This is especially common in older cars that have been exposed to the elements for long periods of time. To clean a dirty lock, you can use penetrating oil or WD-40. If the lock is severely corroded, you may need to have it replaced by a professional locksmith or mechanic.
4. Failed transponder chip
Some car keys have a transponder chip embedded in them that communicates with the car’s ignition system. This chip allows your car to start without having to insert a physical key into the ignition itself. If this chip fails, it can prevent your car from starting even if you have a perfectly good physical key. In some cases, you may be able to have the chip repaired or replaced by a professional locksmith or mechanic. However, in other cases, you may need to get a new key from the dealership.
5. Faulty ignition switch
In some cases, the problem may not be with your key at all but with the ignition switch itself. If you find that your key will turn in the lock but does not crank over when you try to start the car, then chances are there is an issue with the ignition switch and it will need to be repaired or replaced by a professional mechanic or locksmith.
