06 toyota avalon w/ smart key

any one done this before i need some help to work on this car wiring  diagrams what kind bypass need to use

The dealer-installed OEM remote start has poor range, a 10-minute runtime, and also shuts off the car when you open the door. There are several bypass modules to use an aftermarket remote starter with a pushbutton Toyota, but the best one (by far) is Fortin's KEY-OVERRIDE-ALL. If you want to see all the available modules on the market, go to: www.bypasskit.com www.idatalink.com www.ifar.ca In all cases, you can go to those sites, and read the install manual online to see what's involved. The key-override-all costs about $5 more (wholesale) than some of the other modules, but it's well worth it. Installation time is reduced, you don't need as many relays. Best of all, unlike all the other modules, you won't have to cut the car's brake wire, you'll only splice into it instead. The other modules that have you cut the brake wire, if your connection should fail and come apart, the car won't start and would have to be towed. With the key-override-all, if your connection fails, it's only the remote start that'll stop working, but the car can still be driven until it's fixed.
