So my drivers side door handle broke and I bought a new one. I removed the handle and the tumbler. Question is, can I just pop the old tumbler in the new door handle? Is there any trick or anything I need to replace?

Thanks in advance...

insert key in the old broken door handle. the key stays inserted in the keyway. remove the screw at the other end. observe how the coil spring is installed at the end of the tumbler. remove the key, wearing the tumbler assembly. insert this old tumbler assembly in your new handle. install coil spring, install screw. done
