I have an old-school Code-Alarm TW1 system (remote start and security system) in my 2004 Nissan Xterra.
It has been working great for years, then all of a sudden the remote starts flashing these two "Z's", and the problem is that my alarm works fine, but the car will not remote-start. I called up Code who said that this means the alarm is in "valet" mode, and I need to turn the key to on, and flip the valet switch.
The only problem is, I don't have a valet switch - I called the installers, and they said everything is done with the remote. Only problem is, they don't have a users manual anymore so they can't help me.
Can anyone give me an idea as to the sequence I need to go through with this remote to get my alarm out of valet mode?
