I guess its a common problem for xterras just to die when driving huuh lol.... just like all of you. i was driving and mine died at a stop light to lol.... people keep telling me that it might be the timing belt or distributor ( if you remove the distributor cap and someone turns the key a little, if the rotor spins that means the distributor took a dump.. and if the rotor dont spin the timing belt took a dump... i will be checking this out to see if its true this weekend..

Do you get any dash lights when you turn the key on? If not, you could just have a dead battery.

If you have the key code and registration showing prood of ownership. Or you can call a reputable mobil locksmith that can come and make a key for you cylinder.

Most likely the cv joints need to be replaced. Also check struts.

You don't want to turn the security system completely off, besides there really is no need to. To arm and disarm the vehicle simply use the key in the drivers door. When you turn the key and lock the car the system will arm after about 30 seconds. When you come back to the car and unlock the car with the drivers door lock cylinder the system will unarm, just the same as if you were using the remote. If the system is unarmed and it still wont start you probably have a NATS issue with the key. This is different than simply disarming. You can't shut off or disarm the NATS system.

the anti-theft is being set off. use the remote key fob to turn off alarm.
