Exploring Immobilizer Bypasses

Why Bypass?

If your thinking about purchasing a remote start for your vehicle, then you might require an immobilizer bypass.  These devices may be necessary when adding a remote start on mostly 2000 and up vehicles.   If you are unfamiliar with these devices, they are a must for any vehicle with a chipped key.  The way it works is the “Chipped” key is supposed to communicate electronically with your vehicle,  just as the teeth on your key communicate with the tumblers in your ignition.  When you install an aftermarket remote start, there has to be a way for this connection to remain intact.  That’s where the bypass comes in.  It tricks your vehicle into thinking the key is in the ignition allowing the motor to turn over.  Without the bypass, your vehicle will recognize that there is no key in the ignition and will start and immediately die.

Depending on the year, make, and model of your vehicle, you will require different software that is pre-loaded on the bypass.  To make things simple, you always want to try to get a bypass that already has the pre-loaded software for your vehicle.  When you program bypasses, they will require one or two keys to program.  Some will even require you to use one at all times during operation.  If you go with the iData Link ADS-AL CA, then we can actually pre-program your car software into the module at no additional charge.  Convenient right? There are also combo modules.  These give you transponder override as well as some other functions such as door locks, trunk pop, dome light trigger, tach sense, ect.

Having personal experience with these modules, I can safely say that installing a remote start with an immobilizer bypass is not a easy task.  It involves splicing into the main electrical components of your vehicle.  One wrong move and you can cause serious damage to your vehicle such as deploying your airbags (Oh yes, it happens).  Although vehicle specific information is available, professional installation is recommended.  Now if that’s the way you roll, then go out and immobilize your transponder!
