I recently got a new fob for my 2001 nissan xterra and when I go to lock the doors using the key fob, the X won't honk. The parking and tail lights will flash but no honk. I've googled and searched on the forms and I've read people saying to press and hold the lock and unlock buttons until the lights flash to re-enable the horn, but when I try to hold the two buttons nothing happens. The key fob is not the original fob that came with the Xterra, but it is an official nissan key fob. the doors do lock and unlock, just no horn. When the steering wheel is pressed the vehicle does honk, it's just when using the fob. Does anyone have any suggestions??? I've never tried the panic button on the fob, I'm afraid that it will go off and I won't be able to stop it. Thanks.
