hello, about 6 months ago I replaced my steering column and a few days after that my security module and central locking system went. I got the locking system fixed, ad the security module replaced, but when I tried to use my old remotes on the other module they didnt work, I tired to porgram it throuhg the valet switch and you can hear the noise as it accepts the code, but will not unlock or lock the doors. I currently have the remote thats 315mhz, do I mean need the 433mhz one? if anyone knows please respond, thank you!
