Additional Steps for Push Button Start Vehicles

Alternative Methods for Specific Vehicles

For vehicles like the Nissan Altima, Toyota, Ford, Honda, and Subaru, another method involves taking out the physical metal key from the fob and rotating it clockwise and counterclockwise ten times. If this doesn't work, a secondary method using a key switch ignition in the glove compartment might be necessary. Rotate it ten times in both directions to reset the key fob.

Troubleshooting Common Issues

Sometimes, the new batteries might not work because they aren't making proper contact with the control board. Ensuring the battery is correctly positioned and that plastic tabs inside the key fob are not bent can solve this issue. Testing the key fob after making these adjustments is essential to confirm it's functioning properly before you reassemble it.
