avital 4103 engine start troubleshooting

I am a newb here, but have strong wiring/control background/licensed hvac tech NATE certified, anyhow , i just bought a 2005 Chrysler pt cruiser gt turbo edition, Everything on the installed alarm works, except the auto start, its started a handfull of times, what was weird i had it do it while hood was up? than today i bought a new battery for key and it started with hood down, what usually happens is it tries to start goes thru the motions, than just gives up right while it there, i also noticed my rear defroster is not working as well, checked error codes w/3 click key trick, car is clean....i believe it a Avital 4103, its black w/neon like green buttons, is there a way to tell for sure, i have no paper work, where would they mount the mother box, if you will, in this car, hood opened , i see speaker top right side<battery side> with a wire going twords battery, but its buried i cant quite trace it,is the base located where, under the wipers the cowling comes off, and cabin filter is in there/ on the left side anyway?also is there possibly a fuse blown in base ? im lost , its confusing when it does it sometimes, and not again? very strange, the defroster seems to have something to do perhaps with it? thank-you in advance, enough from me...



here's the key

on the back has 800 number and battery code, forgive my eyes, what appears to read d-eazyside474S if that makes sense??please advise, thanks in advance guys...

so it starts everytime with the key in the ignition when using the remote start?

yes, thats the only time,and the defroster was just a fuse, was burnt out replaced, has nothing to do with this, where do thry hide the brain modules in pt cruisers? i want to be sure of model, numbers off kep wont help, would they?

If theres a siren under the hood its going to be a 5103 or if its an older unit a 4400. Is your key grey or black? If its grey and it only starts with the key in the ignition its not a problem with the remote start but with the bypass module. If the key has to be in and on then it sounds like a bad connection on the ignition wire. Do all the dash lights come on when you remote start and no key in the ignition?

you are 100% right it is a grey key, siren under hood by driver seat close to window,and i went to alarm /rim/stereo shop yesterday, the tech opened the pop down panel under steering column and found a grey and white wire spliced and just hanging there off a relay perhaps? ill link a pic, any how the tech was awesome, than the owner came out, the guy was literally only looking at car for 3 min went ti grab a screwdriver to open steering column as he said brain is in there, and owner came out and said i need a new system BLAH blah blah 600$ but alarm works perfect, car does start with key in it, than the tech said ii needed the bypass you mentioned than the owner proceeded to say its 175 plus install i saw the look on techs face thinking its priced high, these guys do bently's all high end cars, so i'm a nobody to them, and they think everyone walking threw the doors is stacked with money, well if he would of let tech open steering column i was prepared to let them install a system and rim package, i had 5k on me,which wouldn't get me much in that shop, but if they treated me right i would of went with them, after-all there's always 100k plus cars sitting out front, so they have to be doing something right?i walked instead, i didn't like the attitude, that's not how you service a customer,i'm in business i cant imagine being that abrupt and still having work the next day anyhow,they think its old and possibly had a third key under in the column area to recognize code?if that makes sense,let me get you a pic, also should i open the column and see whats there, possibility i can take my spare place under car with the magnet holder deal, and that would work as intended? i need advise and you seem to know your stuff, i really appreciate it if anyone lives in bergen county n.j. drop me a line and i'll give you the job!!or ill attempt myself if easy enough i heard the bypass has like 30 wires, but you don't use them all,i'm hoping hooking that spliced cable up and a key would do it, that's obliviously the break, but i mentioned that there's been a handfull of times the auto start worked with hood open and close????so i'm lost, off to pics i talk alot..i will post when it hits my email, i don't know why its taking so long i've been waiting 30 min and sent to 3 different emails,lol gotta love apple

The 5103 and 4400 are visually identical except for the actual model number stamped into the brain. I'm guessing there is already a key in a box or bypass module of some type installed in the vehicle. Its 100% necessary to have one or the other to allow the remote start to work. It would be ridiculous to install that system without the remote start portion connected. Its a waste. Take the shroud off around the steering column and look for a wire or loomed wire wrapped around the ignition cylinder close to the end where the key goes in. More than likely held in place with a zip tie or electrical tape. Also, try to trace the wire that "appears to have fallen off a relay" before you connect it to anything. Its virtually impossible for a wire to fall off a relay unless its come out of the crimp terminal. Post the pics when you can and any info on that loose wire and where it goes. As far as the hood open/closed, more than likely the system was installed without a hood pin. Either that or the hood pin is corroded to the point where it doesnt function properly.

so i don't need a bypass module? its probably those 2 wires that were hanging in the panel that drops down under wheel, grey and white wire, they look to be coming from a relay of some type ill try again tyo get pics up, for some reason my phones not sending them??

-------------
2005 pt cruiser gt turbo

Does it start with the key in the ignition and not turned forward?

i think you have to turn forward to on position, ill try tomorrow and let u know,thanks

-------------
2005 pt cruiser gt turbo

No i was wrong i dont have to put key into on position, all i have to do is put key in ignition, i don't have to turn anything on, it makes a series of clicks,starts ,every-time, than a few moments later the dash lights up?wife changed my password so im having hard time getting phone to send pics to computer, i wish i had a day to just do thing instead i run in and out, and try to get 10000000 things done,lol

2005 pt cruiser gt turbo

ok this was weird, the only thing i noticed, i'm no expert, but this was zip tied around starter key column with no wires attached,like they ere cut off for some reason, why would someone disable it purposely, i heard to give me the spare key, if that the case ill use my spare key and wire what i have to and get another if anyone has a idea or clue PLEASE chime in, thnax fellas,














thankyou

is this the "brain"?



-------------
2005 pt cruiser gt turbo

What youre holding in the one pic is the sentry key chip from a 555C. Its basically whats inside the head of your key. Looks like the wire got yanked out of it. You can do one of 2 things. You can remove the heat shrink and try to solder the 2 wires back on. or you can scrap that unreliable bypass for a data bypass like an idatalink ADS-TB. The brain of your remote start isnt in any of the pics but at this point you really dont need to access it.

so your saying that's a bypass? and those 2 wires grey and white go inside it? i have great soldering skills?

-------------
2005 pt cruiser gt turbo

how do i wire up that new bypass look like plugs go into it, remember im a total newb so the easier the better,thanks for your help

-------------
2005 pt cruiser gt turbo

oh your talking about that thin thing i was holding that was wrapped around key inset with a zip tie, thats a bypass????

-------------
2005 pt cruiser gt turbo

ok thanks, it worked, but i couldn't solder that wire that was wrapped around that tip, like ultra thin piano wire,if i have problem in future, can i remove that wire and wrap the two copper wires <grey/white> around instead, i can make a much more secure connection as i'm worried that wire will break someday, but i zip tied everything secure and IT WORKS!!!!! THANKS,please let me know if i can use copper wire, i already found out i have to use heat shrink tube i tried to electrical tape it real solid,must of cut communication off, be, removed,shrink tube and sucess

-------------
2005 pt cruiser gt turbo

The small box that the wires come out of is a relay that activates the chip thats covered in the heat shrink. If you have problems later on you can try upgrading the wire but if it continues to give you issues I would replace it with a data bypass of some sort

this happens to me all the dash lights come up if I start with remote but nothing when starts with key and the shifter is locked my car is 2006 Toyota Camry 2.4L A/T. one thing more when i start it with remote and i get into the car put the key in turn to ON. the moment i step on brakes.car turns off.... :-(

Sounds like you severed the power to the ignition switch or blew a fuse.

If you can't start/run the car with the key, the remote start is going to turn off when you step on the brake (it's designed to do this) and so will the car because the key isn't working.

Onlyzahid.
Check fuses in engine bay, either that or ignition switch failure.
