Why's my INFINITI Q50 keyless entry not working?

If the keyless entry for Your INFINITIQ50 isn't working, the first thing to check is the battery. The fob takes a small round battery that costs only a few dollars and it's easy to replace. If You have recently replaced the battery and now the keyless entry won't work, the fob likely needs to be reprogRammed. You can find instructions for how to do this in Your owner's manual or online. If it's not the battery and the fob has been reprogRammed, it could simply be damaged internally. The receiver or transmitter could be faulty or the wiring might be loose. The issue might not have anything to do with the keyless entry fob though. The fuse might have blown for the control circuit or the antenna or module for the keyless entry system might have failed.
