Transponder keys and car key remote fobs are an excellent comfort feature to have, however, they all stop working eventually. Regardless if it’s only a dead battery, you’ll know that your vehicle entryways will not open with the remote.
I’ll show you various reasons that a keyless entry remote may stop working, most of them are simple to fix yourself. The most common issue with car key fobs is a dead battery, in which case replacing the battery should fix the problem.
However, these things below you will need to pay special mind to when you experience a none-working key fob.
Things to do first

- Replace the key fob battery.
- Disassemble the key fob and check for any broken contacts or misaligned buttons.

Are you sure your car key fob is not working?
It is an essential tip that won’t matter much too many individuals, yet the first step in making sense of what’s going on with a car key remote is to confirm that the issue is really the remote. Therefore, if you have a replacement remote, you must check whether it works.
If the backup remote can open your entryways, then you’ll know without a doubt that there’s an issue with your main remote. Now, if your backup remote doesn’t work, it may have a malfunction or there could also be a mechanical or electrical issue with the entryway locks.
So, you must check and ensure that your physical key, or emergency valet key, can operate the locks.
What if I have a push-button ignition?
Many modern vehicles work when the key fob is close by. Many vehicles often have a physical key for locking and opening the entryways, yet they might hide it. The car fob will usually have a hidden key inside. When you don’t have a physical key, you can check the fob for a switch or release button.
Different issues vehicle owners will see is that most autos won’t have any visible spot to insert a key. Many autos still have a keyhole, yet they may hide it behind the trim of the entryway handle.
With the key fob not working, the best recommendation is to always check the battery and the buttons on the device. When replacing the battery doesn’t help and the buttons appear fine, your next choice is to have it looked at by an expert. Most issues can be internal, and the device must be taken apart to check if the parts work right.
Broken internal contacts in car key remotes
Key fobs experience physical maltreatment than most devices, and they aren’t indestructible. The two main failures are the battery terminal contacts and the buttons like I mention above. Even though there are many ways they can break.
The ideal approach to check is to disassemble the remote and do a visual assessment. To tell if you have broken battery connector terminals, you will see them loose. Then carefully soldering them back may restore your wrecked key fob to working service.
If the battery terminals don’t look loose, you may find a problem with the soldered buttons. Soldered it back together if you find that they have come loose unless a button has physically snapped off.
Do I have to reprogram my key fob?
Yes. To have the option to open and lock a vehicle, the key fob must get programmed and synchronized. So, for a car key remote to work and have its functionality, you must pair it with the receiver unit in your vehicle.
This will stop anyone from approaching your vehicle and having the option to use their fob to open your vehicle. An expert locksmith can program your key fob quickly and cheaper than the cost that a dealer would charge you.
