Car Remote Not Working?

Key fobs, also called remote keys, have become more and more popular over the past couple of decades. Their main selling point is the convenience of locking, unlocking, and even starting the vehicle from a safe distance. However, these electronic devices are not without drawbacks. They are known to malfunction or otherwise not work. If your car remote is not working, then check out this article brought to you by Top Atlanta Locksmith. We will review some possible causes and present a solution for each. You are also invited to call Top Atlanta Locksmith if you prefer a certified locksmith’s assistance. Top Atlanta Locksmith is available now with 24-hour emergency service.

Are You Sure It’s the Key Fob?

If you are aggressively clicking the buttons on your key fob and it is just not doing its job, then your first thought is probably that the key fob is broken. However, sometimes the issue might be a mechanical or electrical problem with the car or door locks. Before you jump to get your key fob replaced, verify that the problem is actually the remote.

Bring out your backup key fob if you have one and try to lock and unlock your doors. If it works just fine, then your primary key fob is probably problematic. If the backup key fob does not work, then try the physical key. If the physical key works, then the mechanical aspect of the car is fine but there may be a problem with electrical components.

Check the Battery

You should still verify to make sure, but most key fobs use category 4 button cell batteries. You can determine the battery type by checking your manual, contact a local car dealership, or just open up the remote and check the number printed on the battery. These are small coin-shaped batteries that are not expensive and can be found in many hardware stores. 

You can evaluate the battery by using a multimeter to check the voltage, which should show around 3 to 3.6 volts, or you can simply change the battery since they are not that expensive anyway. If the remote works after you’ve changed the battery, then congratulations! Otherwise, continue reading.

Broken Contacts

Key fobs are relatively small electronic devices. That means they are extra prone to breaking. Two common points of failure in a key fob are the battery terminal contacts and the buttons. Are the buttons clicking in and popping back out correctly? If so, open up the remote to take a look inside. Try adjusting, cleaning, and reassembling the buttons. If the key fob still does not work, then check the battery connector terminals for broken or loose parts. Loose parts can be soldered, but broken ones mean you probably need to buy a new key fob.

Reprogramming the Key Fob

Key fobs work by sending a signal to the car. In order for the communication to work, the key fob and the receive in the car must be paired. Sometimes, the programming will malfunction, and the key fob will have to be reprogrammed. There are plenty of tutorials online on how to reprogram key fobs. The experts at Top Atlanta Locksmith also offer reprogramming service around the clock.
