How to fix a door lock cylinder?
 

Hey all, my daughter came home a couple of nights ago and told me the door lock cylinder had been pushed into the door. Not sure if someone tried to break in or if it was loose and just broke or what. Wondering how to fix it? Do I need a locksmith? Or can this be done DIY? TIA!

If the door can still be opened (unlock using the key fob) or can be opened from the inside (getting in from the passenger side), you'll have to remove the inner assembly and see what's going on.
Below is the procedure for removing/installing the door lock cyclinder:

And here are the instructions for removing the sub assemblies:

Thanks! That's great info. I'll take a look tomorrow.
