Key fob working intermittently

i would still get a free load test at an auto parts store, and put a fresh quality battery in the fob to eliminate low hanging fruit.
do you have a second fob?
maybe there is a wiring issue under the dasy behind the switches

 

I second that you should replace the battery in the fob.

 

you could be right, and that's going to be a much deeper dive, especially without trouble codes.
worth checking the voltage at the jump point too.
any chance of rodents chewing on wires?

 

What module would be having the issue The keyless entry alarm module that sort of thing That's iffy If anything you got a mouse in somewhere and it's chewing wires possibly but I would definitely check my fob batteries Make sure I have a red light and pushing any of the three buttons and if there's any questions about the condition of the case you can buy a set of cases online for like $8.99 in black that match exactly your old credit up rubber button thingies you have now if that's the case You might should do that Don't lose your transponder chip in each remote that red light should be consistent with the key button in the out position you'll see that red light on your remote lighting quite often when it's not in the slot it's always hunting for that key to make sure you or it is there and it's okay for the car to be unlocked and to run when commanded if you have SKS and that key button

 

congrats!
