I am have a key that will lock/unlock the doors but not lock the glove box or open the trunk. Is there anywhere I can buy 2 used front door handles and a trunk lock along with a key? Has anyone used a locksmith to make a key to open both the glove box or trunk. I am getting really frustrated!!

just take your VIN to MB dealer and have them cut the keys that you need. That is providing no one has changed the keyways or locks.
Your door key should open all locks. Sounds like you have the valet key and not the master
