My remote keeps getting out of sync(i think).first of all my buttons quit working and i had to keep locking/unlocking manually.then when i went to open it manually only the driver side popped up(usually all of them popup,cant superlock or roll up windows with the key either). i heard to resync all you have to do is do a manual unlock while you are pushing the button.it didn't work. so i took it in and they said they did what i did and got it to work. it happend again 1 day later. what could be the problem.i asked the guy a the rr store if it could be the sensor on the key cylinder he said no all the sensors are in the remote. is that true? does it sound like the remote is the prob. any input would be greatly appreciated.
