hey, need help here, lol

i recently lost my remotes for my concept 100 and rather than pay for 2 new remotes i thought i would mod the system to fit my concept 300 black box and remotes

i got the diagrams but i'm not sure if something is not compatible or there is an error in my concept 300 diagram

the problem is that nothing really happens, the LED stays on insted of flashing, the indicators will flash when the buttons are pressed but the doors dont lock or open, the immobiliser and alarm dont arm

any one know why?? i'm really stuck and frustrated

you might be in vallet mode, make sure that valet mode is not on.

if its in valet mode would it not still lock the doors and start the car? it is a system i had fitted to another car, is it possible it needs reset to the different sensors? concept 100 piezo sensor is there, and the concept 300 dont have one. also c 100 has a glass tapering mic and the c 300 has a proxi sensor 3, could this be the problem?

just in case how do you switch off valet mode??
