Hello and welcome to JustAnswer!

It sounds like the repair most likely was not complete. You mentioned a new key, I'm assuming that you replaced the key along with the other parts. I'm also assuming that you didn't have the car towed to a dealer to have the key programmed, in which case it will cause what you experienced.

Was the key not programmed?

You are right, new accompanying keys not programmed. This assumes that key cylinder has some kind of internal solenoid electromagnetically locked out by car ECM, yes? Will dealer program new keys according to VIN on current registration? And, if so, will this affect original fob's abilty to remotely lock/unlock doors and defeat security?
Expert:  sprinkles08 replied 10 months ago.

The original keys can be erased manually but programming others will not affect them if you don't want it to.

The keys are programmed using a scan tool. The PIN to allow programming is obtained using the VIN.

Limited funding here, currently, so typed dialog must do for now. Must they have the vehicle as well?
Expert:  sprinkles08 replied 10 months ago.

Yes, the vehicle has to be at a dealer for them to program the keys to it.

Must it go to Chrysler or Mercedes?
Expert:  sprinkles08 replied 10 months ago.

Either would be able to program it.

I have neglected to tell you throughout all that this ignition and keys , brand new mind you, is from private party sale and not from dealer.
Customer: replied 10 months ago.
Have been told by local locksmith that ignition and keys have to be preprogramed from authorized dealer according to VIN and once started after installation, are to all sync up at once. Basically rendering anything I've done to this point, useless.
Do you agree with this assessment. This is beyond proprietary, especially considering Mercedes was already phasing this system out in their own lines for same year. This has suddenly become much more expensive.

Keys don't come programmed. They are programmed to the vehicle with a scan tool.
