I have been given 2 assa flexcore locks , but the question i want to ask is do you still pick them in the normal way?. They are 5 pin euro cylinders but the key has a hole that runs the the length of the key so that when you insert the key into the lock a pin enters the key horizontally. would i some how have to push this pin whilst trying to pick the lock the normal way?. i haven't tried to pick the lock yet because i thought that the horizontal pin wouldn't be there for nothing. any advice on this lock and tips on picking them would be much appreciated.

thanks
