it sounds like your alarm button is not making proper contact. try using a q-tip with alcohol rub to clean the surface/button on the board. if you get another one keep the one you have as backup, the common way of programming a new key is cloning and this may fail in future.

Take a copy of your title to the nearest Mercedes dealer they can cut you a key using the vin number. But you must show prof that you own it.

get spark plug gaps checked if there is a faulty plug or the gap is incorect that will make it runn badly

Likely a bad ignition tumbler, considering the key "sticking" in the start position. Best bet is to hit the dealer and ask one of their service advisors if they've run into this problem before.

We doubt there is anything wrong with the wiring in your radio. It has been our experience that after market window tint can cause static and poor reception in vehicles that have radio antennas built into the rear window. Removing the tint improves the radio reception but still leaves something to be desired, especially on AM.

Check if the brake lights are working (with ignition on), There is a safety switch operated on the brake light circuit, so you can't take it out of park unless you have the foot brake pressed. Could be the brake light fuse.

the purge valve can get sticky and stick,feel with you hand while engine is running for a like fast heartbeat.If not ,its stuck.Then spray throttle body cleaner in valve at both ends,let dry.Then start engine and check again.you should feel it clicking or with sethoscope hear it.If not replace purge valve.

rough idle can be the cam and crank sensor or the timing has shifted from weak timing belt/auto adjuster. also the idle valve on intake is sticking or and fuel pressure valve is not working properly if engine runs fine at speed then the adjuster on timing belt can be the fault, as the pressure on the engine turning the cams is putting the right pressure on the belt. if it is through the hole speed ranged the fuel pressure could be low. if engine goes in to limp mode or takes time to speed up it can be timiming alinment out and or the cam sesor or crank sensor.
