Boxster Will not start after rekeying

I'm new to the forums and i'm hopping someone could help me with an issue i'm having. I have a 2001 Boxster S that someone recently tried to break in to and it broke my key tumbler in the driver side door. I bought used locks/keys for the ignition, door, and center console off of a parted 2004.

Long story short after changing all key tumblers the car will not start (doesn't even try to turn over). Everything else works fine, the car locks and the alarm arms. My thoughts are it has something to do with the ignition key tumbler and the alarm system. I'm thinking that the car thinks someone is trying to steel it and will not allow it to start. (i did forget to unplug the batter when i changed the ignition tumbler so maybe that's why it locked it out?)

Any help is appreciated.

Porsche keys are three separate parts the key blade, Key fob with locking system buttons, and RFID tag.
Do you still have the original keys? The RFID chip in the key fob has a code which is recognized by the ignition RFID reader. Its transmitted to the immobilizer if the codes don't match the car will not start. Likewise the locking control transmitter just like a garage door opener is coded in the Immobilizer, and the new one probably will not open the doors or trunks
Your options are
1. Remove the Key fob from the old key and install it on the new key blade. Make sure you do not damage the small glass tube in the base of the key fob this is the RFID tag.
2. have the car taken to a dealer and have them save the new key ID into the Immobilizer.

If you just change out the key and tumbler, you will need to swap the transponder from your old key into the new one. It looks like a small pill within the key.
