Bypass Immobilizer? - Toyota Yaris Forums

Lil Abner · 08-18-2010, 09:52 PM

I've been reading the forums, and haven't found a solid answer. My 2009 LB has the factory keyless with immobilizer. Yeah, it's great, but I don't want it. I have a high-end Viper system I'm going to be installing to replace the factory. Being in Michigan, the 1-mile range and remote start is handy (yes, even on my 5-spd), which needs to bypass the immobilizer. And before anyone asks, I also install a custom neutral safety switch just to be safe!

Question is, if I remove the factory alarm module, will the immobilizer/transponder also be bypassed? Or will I need to purchase a transponder bypass kit? Or can I bypass it without an add-on? My mom Camry, I took a key, wrapped it with 8 coils, then wrapped around the ignition, and it worked. Some other wires, but that's the basic idea.

Any help is greatly appreciated.

The ECM needs to see the transponder to allow the car to start, so to eliminate it you either need to do the "bury a key in the dash" or use a Fortin bypass module.

ECM, crap. I was hoping you wouldn't say that.

Thanks for your quick response CTScott!

Which Viper alarm do you have? The new ones are made to work with manual transmissions. No special parts needed. If your car is like mine it came with 3 keys so when I do my remote start I am going to do the key in a box route because it is cheaper and I will still have 2 keys left.

Palmer812, I don't remember which Viper I have. I purchased it 6 years ago to replace my Clifford 8000. It's one of the 2-way pager ones, blue remote, all the bells and whistles. Mine is too old for the manual transmission thing, so I just have my own safety switch that I'll wire in place. I also only got 2 transponder keys with mine, so one will probably be going under the dash for a bypass. The other one will be put in my safe. Hopefully I can get it installed next week along with my other goodies.
