Do you make those to sell? Or are you referring to one you are using.But sure Key-Less is a nice feature - for those who want that and can eliminate the key-switch completely. In my KeyLess system design, it doesn't even add any external switches at all and the OEM switch it uses to trigger only draws <1mA of current vs 140 mA for a Relay Coil.
EDIT: After reading everything, and finding another thread about this, I see what you did. And I found the RFID you were referring to. It's been 20 yrs since I really messed with wiring diagrams and such, so it took a min for my brain to kick in. Nicely done project. Looking into doing it myself now. Thanx for the info.
