Does anyone know what size tamper-proof torx bit is required to get the screws out?

(It's a 2000.)

 

its t10,t15,or t20. the only way to buy them that I've ever seen is in a set that includes all sizes.

 

OK, thanks. I've been thinking about getting a set for a while, so this is a good excuse to do it IF removing those fasteners will help me.

I got the broken key fragment out of the lock, but I must have shattered some of the tumblers in the process (there are empty slots where it looks like they should be). Is there any way to remove the ignition lock cylinder without being able to turn it to the run position?

 

If I destroy the little tab that you push up with the key in the run position, can I pull the lock cylinder out?
