Yes. Although a car alarm may not protect your vehicle it may help protect any valuables you leave inside your car. CarDefender works great in conjunction with any car alarm as an additional and separate layer of protection.

Yes. Although five seconds does not sound like a lot of time it actually is more than sufficient to start your vehicle.

Yes. CarDefender can be used on any vehicle that has an electronic component that is required to run the engine. You simply disable that component. We have installed CarDefender in work trucks, motor homes, sandbuggys, boats, even motorcycles. This includes everything from vehicles with points and condenser to electronic ignition to fully computer controlled vehicles.

Any experienced mechanic is capable of installing CarDefender. The provided instructions are easy to read and very concise. Rates will vary but you should expect to pay for 1-2 hours of labor.

We have yet to have a unit fail. Each unit is hand tested by a technician before shipping. In the unlikely event of a failure, you would need to remove the controller from it's connector and insert the "by-pass plug" that is provided with every unit. This will allow you to run your vehicle until you can receive a new controller from CarDefender. NOTE! Your vehicle will NOT be protected when using the by-pass plug.

CarDefender offers replacement Transponder keys for $24.95/pair (Note) orders outside the U.S.A. please contact CarDefender beforehand.

Simply remove the controller & insert the by-pass plug, send the controller to CarDefender we will erase the old code & supply you with new transponder key with a new code, the cost for this is $24.95 for each transponder pair. (Outside the U.S.A. requires additional shipping charges.) 

NOTE! Your vehicle will NOT be protected when using the by-pass plug.
