Hi there, not sure what you mean by Valet lock, but if I am assuming correctly, I had a similar problem when I got my '98 Boxster. I had a remote key fob, but it wouldn't unlock the boot (or the doors for that matter). I eventually discovered, that all I had was the key, with no remote locking at all. I had an after market one fitted, but still have to open the boot (trunk for you yanks

) manually.
After the garage told me it would cost over A$3000 to have the authentic remote key and boot release fitted, I haven't really been too bothered by the slight inconvenience.
