I have an avital 4103 in my 2004 silverado. It won't unlock the doors and it starts but immediately quits.

hi'

i think the wire that connects to the door trigger for the interior light

a negative or a positive one has been mixed up

if its neg change it to the positive one

if its positive change it for the negative one

the purple or green wire

cheers

You might have put the earth wire on the wrong connection. Try disconnecting the earth and see if there is another point where it might go.

There's a website that has all this information about all this and manuals everything totally free there are many actually but I personally like few like reliable-store... let me know if u need help
thanks

I got this free Pdf manual from an online store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the all the times I fixed the chipper in these 4 years

Your FOB has gone bad. Try your other FOB just to make sure and let me know ....

Manually disarm the alarm by turning the ignition on, press and release the valet switch.

My remote will not unlock my truck or disarm and I put in New batteries. What do I need to do

The Camry you purchased may not be equipped with a power trunk. Press and hold the trunk button for appoximately 4 seconds. The trunk should release if the wire is connected and, you have a power trunk.
The Camry (and other toyotas) require a double pulse on the unlock wire. If the double pulse is not programmed the aftermarket unit will mimic the factory keyless entry. One press of the unlock button opens the drivers door. Immediately press the unlock button again to unlock the other doors.

As an L1 ASE Master tech I ALWAYS advise against aftermarket alarm systems, however the problem you are experiencing is due to an action that is not being taken by the vehicles control modules. The installer should tie into the door control modules or find out why the body control module is recognizing the command for the locking/un-locking action, (hence the lighting response), but the doors are not taking appropriate action. I would have to look at live data in the vehicles control modules to see what modules are being commanded to do what. Take it back to the place where it was put in and tell them to fix it or refund it.

Good luck!

Its not the avital piece that's the problem, it's your INSTALLER that is/was the problem....haha, got somethin wired wrong!! It only does what you install it to do! :)
