Key RFID

[clueless1]

I have only one key for an 01 S. I am afraid of losing the “key” so I have copied the blade to make a spare and in order that both work have attached the RFID from the first key to the ignition cylinder. I am comfortable with this solution.

I would like to install a remote start system. Currently the installation works only when the key blade is in the ignition cylinder and in the ACC position. After much research I believe that the ignition cylinder transponder antenna may be similar to a BMW, in which the ignition wires are hot when they key is in either ACC and crank? In other words, I think that they transponder antenna is not reading the connected RFID because it is not getting power except when the key blade is in the car in ACC.

If that is the case, then I can envision two possible solutions:

First and easiest would be to wire a relay to the transponder ?antenna? in the key ring. But I am a bit reluctant to cut that wire without confirming a previous bypass install, for fear of somehow screwing up the immobilizer requiring a reprogram of the CLU. Has anybody had a remote starter installed and if so how did they wire the key bypass?

The alternative would be to use a key bypass (I have a 556UW lying around). This solution leaves the exact same question: how to do the bypass install wiring. Additionally, I would need to copy the RFID in order to have the ability to start the car without the remote starter (since I would lose a key to the 556UW bypass). Does anybody know of a place doing RFID cloning?

I imagine quite a few folks must have had a remote starter installed. Thanks for any info that can be provided.
