Can multiple vpn connections on a cisco pix have individual pre-shared keys?

I have a cisco pix 506 at our corp office and a pix 501e at one of our remote sites. Is the pre-shared key for the vpn connections defined system-wide or can you use a different key for each site? I can't get the vpn up at the new location. I configured a different site only a few months ago and did not run into these problems. Here is the pertinent part of the config for both routers. Any help would be greatly appreciated.

Corp Pix:
pdm location 192.168.16.0 255.255.255.0 outside (remote subnet)

crypto map to_remotes 90 ipsec-isakmp
crypto map to_remotes 90 match address remotesite
crypto map to_remotes 90 set peer xxx.xxx.xxx.xxx (xxx=remote ip)
crypto map to_remotes 90 set transform-set strong
isakmp key ******** address xxx.xxx.xxx.xxx netmask 255.255.255.255

isakmp keepalive 10 5
isakmp policy 8 authentication pre-share
isakmp policy 8 encryption 3des
isakmp policy 8 hash sha
isakmp policy 8 group 1
isakmp policy 8 lifetime 86400


remote pix:
pdm location 192.168.1.0 255.255.255.0 outside (corp subnet)

crypto map corpsite 90 ipsec-isakmp
crypto map corpsite 90 match address 150
crypto map corpsite 90 set peer xxx.xxx.xxx.xxx (ip of corp pix)
crypto map corpsite 90 set transform-set strong
crypto map corpsite interface outside

isakmp key wathen address xxx.xxx.xxx.xxx netmask 255.255.255.255 (corp pix)
isakmp policy 9 authentication pre-share
isakmp policy 9 encryption 3des
isakmp policy 9 hash sha
isakmp policy 9 group 1
isakmp policy 9 lifetime 86400

Could the pre-shared key hanging me up? I know the key for these two sites are matching on both ends but I don't think they are the password that was being used for the other locations.
