Fix Your Keyless Entry Module in 5 Easy Steps

Step 1: Check the Remote Battery

The first and foremost step when troubleshooting a keyless entry module is to check the remote battery. A weak or dead battery is often the culprit behind a non-working keyless entry module. Here’s how to check the remote battery:

  1. Remove the battery cover on the back of the remote.
  2. Take out the battery and verify its model number.
  3. Use a multimeter to check the voltage of the battery. A new battery should read between 2.7 to 3.3 volts. If the voltage is lower, replace the battery.

Step 2: Check the Wiring

After verifying that the remote battery is not the issue, the next step is to check the wiring between the keyless entry module and the car or home. Follow these steps to proceed:

  1. Locate the keyless entry module. Depending on your car or home, it could be under the dashboard or hood or in the electrical panel.
  2. Check the wiring connections to make sure they are tight and not corroded.
  3. Follow the wiring from the keyless entry module to the car or home to ensure there are no breaks or loose connections.

Step 3: Try Re-programming the Remote

If the wiring is in good condition, the next step is to try re-programming the remote. Sometimes reprogramming the remote solves the issue. Here’s how to do it:

  1. Find the programming instructions for your particular remote. You can usually find them in the owner’s manual or online.
  2. Follow the instructions carefully to reprogram the remote.

Step 4: Replace the Fuse

If the remote is not the issue, the next step is to replace the fuse that connects the keyless entry module to the car or home. Follow these steps:

  1. Locate the fuse box in your car or home.
  2. Use the owner’s manual to find the fuse that connects to the keyless entry module.
  3. Remove the fuse using a fuse puller and inspect it for signs of damage.
  4. Replace the fuse with a new one of the same amperage rating.

Step 5: Call for Professional Help

If none of the above steps work, it’s time to call for professional help from a locksmith or mechanic. They have the proper tools and expertise to diagnose and repair the keyless entry module.


Fixing a non-working keyless entry module isn’t rocket science, and you can easily do it yourself with the right knowledge and tools. Start with checking the remote battery, then inspect the wiring, try reprogramming the remote, and replace the fuse. If none of these steps work, don’t hesitate to call for professional help.
