I was wondering if you would still need the immobilizer chip inside the ignition if the car was started with remote start. Does anyone know?

 

yeah, someone posted a bypass so u dont have to use a key.

ill try to find it :D

 

they have it on amazon.... cheap too and brand new...

 

have u experienced using it?

 

best buy has an 80 dollar module that clones the chip ID so you don't lose a key when you do a remote start. the only issue is best buy has to install the proper software for you vehicle, and the module's not exactly fun to install. if done wrong it can erase all chip IDs from some vehicles.

 

Are you talking about this one? http://www.autotoys.com/x/product.php?productid=6181

556u is basically a storage box that you have to stick one of your keys in.. typically the valet key, the xk05 is the module that clones the key ID

you do need two keys to program the xk05 after flashing it

(best buy car audio installer)

 

yeah unfortunately you need the bypass kit (556u/556uw). i have this kind of alarm in my tc, and i just used my valet key.

 

as did i originally, but now with that xk05 module you get to keep all of your keys.. it just takes longer to install. luckily.. and not so lucky, the xb2 doesn't have chipped keys, it took a little bit of rigging but while installing my remote start i was able to hot wire it :\

 

So after I have the XK05 installed, can I be able to use a copied key (w/o the chip) to drive the car?

What if I installed the 556u using my valet key... can I be able to use a copied key (w/o the chip) to drive the car?

 

no, the modules only power up when the remote start is activated

 

i have the bypass so you can just program the key to it, but i haven't installed it in my car yet because i've been lagging it but when i used to work for a company installing them, it seemed much better than just looking for a really really good place to hide the key. you can buy it online or call this company who is the one that makes it.

that is the one that i have which was the one they recommended me. i got it free so i wouldn't be able to say how much it really is but it's worth it. if you have any questions then just let me know and i'll try to help you out on here.

 

wow thanks for all the info, how long does an install usually take?

 

no problem, it all depends on the installer really... it can take anywhere from 2 and a half hours to all day haha

 

L337Biker also knows what he is talking about. 05_TRC_tC, installation depends on how well you where which wires are which with a test light, but i'll say a good 2-3 hrs on a well clean job.

 

I have the 556u in my car. I used one of the master key. But when you put it in the casing, you have to clip off the ends of the 556u casing just to get the key to fit. Not sure if you can use the valet key instead of the master. I still think you need some sorta key in the ignition because if i don't put a key in it, i can still get off on first gear and all but the steering wheel locks up and once i hit the brakes, the engine dies.

 

multimeter ;) air bag horror stories lol

actually best buy had an employee die about 6 months ago due to airbag deployment.. idiot was stripping/testing/popping wires trying to find speaker wires...

probably the biggest pain about the install will be working around the knee airbag. luckily there aren't too many other wires required to make an alarm work in the tc.. door triggers and lock/unlock pulse.. flashing lights if you want, that kinda deal. it's just testing the wires and making sure they're correct

you can use the valet key, that's what was done in mine originally.. it starts the car so it'll start the car w/ the 556u
