Key remotes don’t work anymore

[Dr. Kill]

Thank you everyone for your suggestions.

I managed to get it working again.

I replaced the battery but that didn’t help, then I tried to do the key reset procedure found in the manual, that didn’t work either. Then I tried a whole bunch of derivations of the key reset procedure, varying amount of times I pressed buttons, length of time holding them down, and other combinations of locking, unlocking, and placing the key in the ignition. The good thing is that one of them worked, I am just not sure which combination actually did it.
