Bypass kits
Tuesday, September 13, 2005 11:59 PM
does anyone know anything about these bypass kits that people use for remote starters? If so, do you have to have a remote starter, and does it over ride the use of a key? How do these work? And also how does it effect you're theft system, does it override it, or what?

NEW SIG COMING SOON FOR 07'!!!

ok are u buying a alarm and remote start or just trying to put in a remote start? anyways the results are the same. when u hit the start button, the car starts. try putting the car in gear without a key. if its an auto its impossible. also, when a car is remote started, if someone touches the brake pedal wout the key in and on the car shuts off.

he might be talking about something with remote start + manual transmission.

I'm pretty sure there's something special you have to do, and install shops aren't supposed to do it...

well atleast where i live its illegal to put a remote starter in a manual transmission car but what he's talking about is the immobalizer. Not to sure if his car needs one but if you go down to any local install shop they can check it out for you. I needed one in a '03 pontiac so chances are you may need one if your car is 2000+. Just phone a shop and ask about an immobalizer and price.

this guy at school has a viper alarm for his 03 cav (manual) he got remote start and had 2 sign a waiver at some audio store. he told me that they charged him about 75 bucks more for the bypass for his car. they said because it was a manual car they needed the bypass and the waiver had 2 b signed because they were not going to b held responsible if he remote started his car and it was in gear. but i bet most places might do it. as for key issue im not sure.

Most remote starters have a wire that is run to the parking brake, so that it won't start the car unless the parking brake is engaged. This is for manual transmissions so that the car doesn't start and then roll away. The module you are probably talking about is the Passlock module. I would say it's probably going to cost you around $50. It sends a signal to the theft system so that it allows the car to start without a key in the ignition. Like said above, if the brake is pressed or the hood is opened the remote start will turn off for safety reasons.

I know people that have installed remote start systems themselves on manual transmissions. Along with bypassing the clutch, the parking brake sensor and/or ones installed in the slots for 1st and reverse gear i know they were going to use for the system to know if the car is parked in gear or not. But as for automatics, yeh, it's just the bypass module like everyone has been saying.

Ok.. first things first..

PASSlock is the system. It's an immobilizer. When you insert your key into the lock cylinder , there's a sensor that reads the resistance of the key itself... then generates what is called the "R-code" based on the resistance (get it? R = resistance... lol... R is futile!!) Once the BCM (or cluster, on 95-99 cars) receives the right R-code, it sends the fuel password to the PCM, and the car will run. If the car doesn't receive the right R-code... or any R-code a all... then the BCM doesn't send the fuel password to the PCM.. and the car won't run.

If you install a remote start alarm, you're asking the car to start without a key. But if you don't have a key in the lock cylinder, you don't have a R-code, so you don't get a fuel password... so the car don't start. So here's the trick.. you bypass the PASSlock system, using a bypass module.

The bypass module is installed to the wires that run from the lock cylinder to the BCM/cluster where the R-code is transmitted. The first time you start the car after installing it, the bypass module learns the proper R-code. The bypass module is also connected to the aftermarket alarm system. When you hit the "remote start" button or sequence of buttons on the alarm remote, the alarm brain tells the bypass module to activate (which it does), then it starts the car.

So... in effect.... the bypass module transmits the proper "R-code" for long enough to start the car remotely... then it goes back to normal operation (ie. protecting the car). You only need the R-code to be sent when the car is started.


There isn't a point to having a bypass module installed unless you have a remote start alarm. Whether it's on an auto or manual transmission is irrelevant, and really isn't what he was asking... so...

LOL

good times...
