Hi,remove and repace the pop-out switch

[hugeal]

Hi,
i broke off my model a ignition switch in the lock. I took my needle nose pliers and pulled out the stub of the key. I cant find the handle end of the key. I understand i will have to remove the lock in order to see the key code, a-xxxx. With the key code i think a locksmith can make a key. Would someone take me step-by-step on just how to remove the pop-out switch so i can see the key code.
I would like to suggest all model a members copy there key code so just in case your key is lost, a easy replacement can be made. Thank you.
