I have a curiousity question for all you installers.

I'm a professional installer and happen to be very knowledgable about the transponder systems that are installed on the newer model cars (i.e. Honda's, Nissan's, etc.).  My sister in-law has a 2004 Honda Accord that was stolen right in front of her house.  She has the transponder system on the vehicle, and I wanted to know is there a device on the market that is used to replicate the signal of the factory key or is their a secondary work around to possibly steal the car.  The only other thing I could think of was that someone towed the car away, but this is unlikely.

Any thoughts based on your professional experience?

The Immobilizer is only a single pointof immobiliztion for the Honda's ( as I undestand it ). It will cut fuel to the injectors and that is all. It will not disable the starter solenoid or disable the ignition wires. If someone knew the system well enough ( or had a spare key ) they can get away with the car. Could it be someone from the dealer ship ?? Was there broken glass anywhere on the drive way to indicate a break & enter ?

Travis,

You are probably aware of what is involved in basic RS install, and what it takes to use one of the bypass kits to circumvent the OEM system.

I would ask you to take a minute to consider the fastest way, and method to install the unit with the least amount of wire cutting to simply get the vehicle started.


I stress the words STARTED, this does not mean the vehicle has to be running for very long.

Normally we use our ETD unit to make a key, or use a scan tool to *Interogate* the system as to the valid code, then from there.

It's a matter of making the key, and driving away.

I think the biggest thing people forget, is that its all about time, or the lack of.

It would take me under 5 seconds to open the door, it would take me another 30-60 seconds to scan the ECU. From there, it would take me another 2-3 minutes to make a key.

From there, another 10-20 seconds to get back to the car and drive away. That is using the key method.

If it was a bypass, then it would take aprox. 60-85 seconds to do a bypass.

It's all about time, and how much we need the vehicle back in the impound.

If we are unable to start the vehicle in our 5 minute window, then the vehicle is simply towed, with U clamps.

That amounts to 10-20 seconds, without obstructions of for, or aft of the vehicle.

Sorry for her loss.
