How do I unlocked my computer?

I noticed last time I changed locks if I tightened the 2door knob pieces to much I couldn't use lock at all.loosened just all and works no problem

The tumblers probably jammed in the lock cylinder.
You could try a spare key to make sure.

Most likely needs to be re matched to the car.

This information is for the resetting of a previously synchronised key to match the security system after batteries have been removed or replaced. This information does not work with new keys which it seems must be taken to a person with a key synchronisation device [or a super-ripoff-expensive MB dealer]

The computer that controls the trunk and hood latches is under the seat, as you discovered. Unfortunately, this is not a good position to have a computer when moisture enters the car (to say the least). The Boxster being a convertible makes it especially susceptible to moisture problems here. I've seen the same trunk/hood latch problem, and it had to be reset by a dealer tech. Took about 3 minutes. I suspect your additional problem to be a) a wiring short when you did your microsurgery, or b) you activated the Boxster's anti-theft defense. Again, I suggest professional help. For the car  ;-).

BMW 7-Series - Key Remote Programming
Three methods to try:
Method 1:
1. Working from within the vehicle and with the doors shut
2. Turn ignition to position 1 and back to off within 5 seconds.
3. Remove the key from ignition and press and hold the unlock button for 15 seconds during this time press the key lock button 3 times within 5 seconds.
4. Release both buttons.
5. Doors will lock and unlock to show correct programming has occurred.

Method 2:
To do this procedure you need to have one working key and one key that needs to be programmed.
1) Get in and close all doors.
2) Turn on the ignition and turn off quickly. (No more than 5 seconds) to start the process. Next action must take place within 30 seconds.
3) Remove the 1st key.
4) Hold the key up near your left shoulder (this is so it is closer to the remote receiver antenna.
5) Hold down the unlock button and press the lock button 3 times. Release the unlock button and the doors lock which confirms the operation.
6) Quickly repeat steps 4 & 5 for key #2 etc.
If it does not work, try doing the keys in opposite order. Key 2 then key 1, vs 1 then 2.

Method 3:
Alternate if you do not have a working remote
1. Turn key to position 1 five times very quickly 2. Remove key 3. Hold unlock button then press lock button 3 times, release unlock button.
4. If you have another key do the same button pressing within 30 seconds 5. Turn on ignition to finalise.
PLEASE NOTE: This programming procedure programs the remote control part of the key. Any transponder chip for the immobiliser (starting of car) will not be programmed and must be done by a specialist.
