Cadillac XLR Remote Starter?

Is it possible to do a remote starter on the 05 XLR ?

This car starts with a push button. As far as I know it cannot be started with a key and the driver MUST have a remote with him. If anyone has ANY info on this car I would appreciate it. Thanks

sounds extremely easy to me..only q,is the driver's fob active,or passive?i am guessing it has a batt?
put a relay on a fob in the car(on the batt),then 'push the button'without more info,that sounds like it would work..unless you have to program the fob each time..
or some other problem unforeseen.. try it,just take out the battery,sit in the car,put the batt in the fob,push the button..keep track of what the door locks do..
i figure it has to be active,a passive system would require one hell of an rf output from the car at all times.. and with cancer from cell phones,the cat crawling on the hood would drop dead in a sec!(cell phone cancer is BOGUS(I think)!!)but you get the idea..then again "MUST"..check again about the no key thing..there has to be a bypass of some kind..remote batt dies,falls and gets hurt(indestructible remote? who has ever seen such a thing?)
i guess what i am getting at is the same thing the above post says..just giving people something to think about.. anything is possible,anything can be re-created..this is what ALOT of us do every day..i have always been a never done it before person,and within 2 mins,i will know if it is or isnt possible..try the batt thing,if it is passive,you could always make a van de graff(i think thats the guy,no rf/em in-or-out.) cage/box..then use a solenoid to 'open' it,THEN 'push the button'the pushing should be the easy part,again electrically,or physically..i need to see a switch,but if i had a cust that wanted,or was willing to do it,i think actually seeing the button operating in the car would be the greatest thing he/she ever saw!
just a thought,do they OFFER rs?like the Malibu? or did they stop that?
L8r people..

The fob has a battery but only requires that it be in the car. The car is capable of sensing the presence of the fob and will allow the car to start if that is so.

well what i am saying,you can just put a remote inside the car,solder a wire to the batt connectors,then just make an alarm connect the batt,then another relay(or however many it takes to re-create the switch/button for start,and viola!
now,if i know how they work,which i think i do.. you dont even need a remote start alarm! just one with a latched output,and another momentary..
point being,if the fob isnt powered up,the car doesn't know its in there..there are some security issues as well,in other words,the car is DRIVABLE at that point,so some thinking has to be done..pm me,and i will be more than happy to help you figure it out..
and,does it unlock the doors when it senses a fob,and then,does it re-lock when started,or just in gear?
thats just the beginning,but i dont know of a vehicle that CAN'T be done,just ones that people dont want to spend the money on!like the bimmers with the ir key,the best iv e heard is having to put another ign system in the car,and creating a switching network between the two.. ANYTHING CAN be done! you just want to have to do it bad enough! You have to realize a little of my background,i've built planes,a Thorpe t-18(experimental,all aluminum)
a Mitchell b-10(ultralight,doped fabric,wood),
a very-eazy(all fiberglass,you must have heard of Burt Rutan,this was one of his first broad ventures)
and a few boats,a hirshoff (sp?) 55 ft fiberglass dual 50ft mast sailboat,
and throw a few houses in the mix,from electricity(DUH),to plumbing,whatever..
I have been taught from an early age to make things happen.. it can be done..rest assured it can be done..
remember the Aztecs performed brain surgery,and alot of people survived!

Your point about the fob with the battery is a good one. I'll try that

Like i think i pointed out,i have not actually worked on one of these fob present cars,just a radio in a prius..
let me know what happens! curious..I am sure i will run across one..
and i think i also mentioned something about not needing a real remote start contraption,just one with two outputs..
something to try..
try just VERY quickly,but make sure it 'hits',push the button..what i am trying to get at is;is it like the range rovers? you just turn it to start,and when you let go,it cranks until its started(without the button/ign actually being in the start position?)
so you would only need one latched output,for the fob batt,then just a momentary/pulse or whatever whoever calls it..
remember,you can build a latch from the diagrams at the left of your screen
<<<<<
look under 'relays' i am pretty sure i saw one there,
and maybe look into a timer as well..again,something on the left
<<<<<
if you are using an rs alarm,you will probably have to use a tach..if its like a Buick i did,the volt sense wont work..this Buick took like 5 secs to get back to 12.xx v!
a computer controlled alt..this bit me on this car,the one car in quite a few years i decided to use voltage,my alarm tech guy always said 'its a great thing,always works!' well,until your voltage takes 10+ seconds to get to 14!! just do a quick mm check,but i would think it would be a long ramp up..
long enough for a quick note huh..just trying to help you think..I just hope something i said helps!
sometimes i am a bit too passionate,but i feel the only way to get it right,is to go too far!like an alt guy on another post,death probably wasn't the most appropriate thing to say,but alot of smoke can make you wreck!

The two problems I may have to deal with will be to get the car to shut down after the run time and the relay to push the button to start. If it's a simple negative or positive pulse then no prob. My fear is that this is a data return signal that supplies a modified pulse.

ITEM NOTE INFOTECH #
Immobilizer The design of the keyless access with push button start system is to prevent vehicle theft by disabling the engine unless the correct key fob is present when attempting to start the vehicle. The system is similar in concept to the PASS-Key® III system. However, the key fob is considered to be the key. Directed has no module at present to interface with this system.    
Special Note This procedure would typically be used when adding a key fob when both the vehicle key and two known good fobs are present.

The vehicle must be OFF.
Open the rear compartment.
Have two known recognized key fobs with you and a new unrecognized key fob with you.
At the rear of the vehicle insert the vehicle key in the rear compartment lock cylinder located in the lower left and cycle the key 5 times within 5 seconds.
The drivers information center (DIC) will display a message: READY FOR FOB X (X = fob 2, 3, or 4).
Place the new unknown key fob in the glove box fob pocket with the buttons facing right.
A beep will occur and the DIC will display: READY FOR FOB X or MAX FOBS LEARNED.
If programming additional key fobs, repeat steps 5 and six, or press the OFF/ACC portion of the ignition switch to exit programming mode.



Doesn't look good man, I don't think I'd be attempting a remote starter in this vehicle

If the pushbutton that starts this car is a plain - or + pulse then it should be pretty easy. Once the car sees this button pressed it will take care of all ignition wires and starter on it's own.

Yeah, but get a starter to understand that, about all you can do is use an AUX output of an alarm to activate it.

BIGGEST problem will be having an active FOB in the car, it will enable anyone to open the doors without setting off the alarm.

Well... yes and no. The way to do this would be to remove the battery from the unit. It's probably a CR2032 or a variant. Now... use a relay to interrupt the battery circuit in the remote. Close the remotes battery circuit using a status output, ground when running, or whatever turns on during the required button presses on the remote. It will effectively shut the fob off when it is not needed, wouldn't it? Be a thought on how to keep the factory security integral.

Anyone else see a problem with this scheme??

Wherever I go, that is where I end up......

I think FACTORY security is out of the Q,but if you put a rs alarm in it,just use it to lock the doors,and if the alarm is set off,the fob should lose the batt..(by way of the same relay,maybe another to shut it off..again,havent thought it out..but i would think if fob is inactive,engine shuts down,doors lock..(again...gotta play w/it a little,but try some stuff..take some notes,and think it through..or post it and let us help think..)
get in car,with good fob..
take out batt..(doors lock? rap off,on?etc..)
put batt in..(door unlock? rap on,off? )
what kinda wires are hooked up to the push-button?
re-create those,w/resistors,relays,etc..do some measuring,not pushed,pushed,both ways(diodes?) or can it be disassembled?(only if it isn't easy to figure out..a last resort..we know how springs act when let free! along with detent balls,levers,contacts,etc...)
just be methodical,careful,etc..
don't hurt the poor car too bad,it's not the cars fault!
haha..
anyway...I would also talk to trilogix..see what they have,but dont expect an answer,just help with what you may,or may not need..i dont think any one place will give you ALL the answer(s)..it is our job to put a few of them together..and hopefully get what we(the customer) wants..
keep us posted..(did I have to say that?)
