Security question

[SVX92-97]

Programmed my 94 pearl factory security system with a two button keyless ride remote. First of all only one button works to arm and disarm, the lock button, and secondly, it only locks the passenger door. I believe my drivers door lock is fine, because when I push it down by hand it locks both doors, and if I lock from the outside using the key, it also locks both doors. Any idea what it could be. I will try another remote first, and then the security module. Speaking of which, these are obsolete from subaru correct? Does one know what goes bad with these modules, and are they fixable.
