Both below procedures use the CLI on the devices in configuration mode and use these values:

<peer_ip> = current peer IP address
<peer_netmask> = current peer netmask
<new_key> = value of new pre-shared key you wish to change to

PIX 501/515
no isakmp key whatever address <peer_ip> netmask <peer_netmask>
isakmp key <new_key> address <peer_ip> netmask <peer_netmask>

1841 Router
no crypto isakmp key whatever address <peer_ip>
crypto isakmp key <new_key> address <peer_ip>
