Key programming problem

Gents I can't get more than one key at a time to work off the remote - as soon as I get one synced the other drops off
What else can be at fault the BECM?

Once you finish the last key have you put the key back in the ignition to finalise the process? That the error I made before I clicked.

Yes even took it in to an Indy and they couldn't get it to work either I have 3 keys and can get any one to sync but it drops the others off its as though it can only hold one key

Meant to say they all unlock and start the car on the key just the remote won't work on more than one at a time

Use the above process to program the key and then do the other key straight after (repeat steps 4-5 with other keys). When you program a new key it will forget other keys so you have to re-program all keys in one sitting if you like. Maximum of 4 keys! Jordan
