Question about Avital Vehicle Parts & Accessories

Open Question

Can I easily swap a malfunctioning Avital 5303i with a 5305L?

I have a 2000 GMC work truck with an Avital 5303i system in it. The remote started operating intermittently and then hardly at all. I purchased new batteries and it didn't help. I purchased a new remote and that wouldn't work so I purchased what I thought was a matching 5303 alarm with the plans of switching out the brains. What I received was a 5305L. I'm wondering how difficult it would be to pull out the 5303 and replace with the 5305. I know there are fewer pieces but I don't have the time to learn to install this so if it's more than unplug and plug I'll probably hire it out.

SOURCE: changed batter remote start not working

Hello, What has happened is your remote has lost its programming.. Just like with most electronics, when something is reset or powered off, or even when the battery dies ....the programming software is lost. The remote has to be reprogramed either by a dealer (suggested) or by an aftermarket outsource..Hope this helps...This could help with almost all remotes.

SOURCE: My alarm will not stop going off

I understand how important sound systems are I own one myself. My advice to you is to see if you can get new batteries for the remote. It may have gotten stuck in antihijaking mode when the remote last worked. If this doesn't work try consulting the dealer which you bought your system from.

If you have removed the brain, I don't see why you need to remove the rest, unless you just want it out of the car. Without the brain the wiring should cause no problems to your car unless there is a bad connection. If you need more info on how to remove the remaining alarm---
remove the siren in the engine compartment. Most everything else will probably be found under dash drivers side. If it has been installed with connectors, remove them at point of connection. If solderd cut at point of connection and use electrical tape to cover exposed wire. You will have one wire connected to the dome light circuit, one to the parking lights, one to a relay to disable the starter. Cut it out and reconnect starter wire. Led, a switch, maybe a button also-not hard but maybe not necessary?

SOURCE: suburban battery keeps dying

locate the brain under the drivers side under-dash area. this may require you to undo a couple of bolts. you will need a 7MM and a 10MM depending on the year of the truck. from there you can unplug the the 6 pin main ignition harness from the brain. it may just be that the battery is no good. a trip to one of the major chain auto part stores can have them check your battery for free. Good luck.

I have a 98 GMC Yukon I need to uninstall a 5303 model Avital aftermarket alarm system/keyless remote. I believe it has malfunctioned and is causing my car not to crank. It will turn over but no spark

Try finding it. Under dash probably.. Unplug the two fuses first, sometimes that works, if it's a high end viper or dei unit then you can trace the wires to the starter. #12 gauge wire pink or red. Should see where it's tapped in or relays hidden under the panel. It shouldn't cost too much for electrical guy to find and disable

Well, if you connected the tach sense wire (violet/white) from the Avital, remove it and use either virtual tach or voltage. It sounds to me that whatever you have connected to the tachometer is sending a signal rather than sensing, causing the malfunction.

Engine cranks will start fine with key remote will not start it

Did it ever work as far as you Know? Some vehicles have a coded key and if the key is not in the ignition at the time the remote is activated it will not start. Some systems have a key hidden in the system and some have a bypass. It is hard for me to tell you which you have as not being the installer. You may have to contact Avital or go to thier web site for more detailed info.
