Keyless remote lost sync

[Viper5]

I was sick of this whole key not working crap, so I went to the store to buy a battery. I popped it in and when I went home, I just did some random stuff and it came back to life. So I think in my case it was a combination of a dead battery and leaving it off for a while.

I think I did something like this:

Locked door, unlocked door, locked door, unlocked door, open door, put key in ignition, turn power on (not starting car), while key in ignition hold down lock button for a couple seconds, same with trunk, take key out, hit lock with door still open, close door, and walah. About 12 easy steps is all it takes. lol

you've had better luck than i. thought perhaps the battery was dead, even though the remote opens the trunk and front lid... new battery but the doors still won't lock / unlock with the remote. the second key works fine.

tried starting the car with the "bad" key, doors... no dice.

sadly i do not have the tag since i bought my boxster second-hand.

hoping the dealer can help.

:ah:

when i bought mine last year all three kesy would manually unlock the door and start the car, but only one had functional remote lock/unlock .

i had the key head replaced (still on warranty)

the key head is dettachable from the the key so you don't need to have a new key cut unless you want or need a second key,

take it from there...
