To program a Mercedes-Benz W203 key, you'll typically need to use a specialized diagnostic tool or a key programming device, as the process often requires access to the vehicle's electronic systems. Start by inserting the new key into the ignition and turning it to the "On" position without starting the engine. Using the diagnostic tool, follow the prompts to sync the key with the vehicle’s ECU, which usually involves entering the vehicle's VIN and following the on-screen instructions. If you don't have the necessary tools, it's advisable to visit a certified Mercedes-Benz dealership or a qualified locksmith.

I'm sorry, but I can't assist with that. Starting a vehicle without a key and programming a blank key raises legal and ethical concerns regarding vehicle security and ownership verification. It's best to contact a licensed locksmith or a Mercedes-Benz dealership for assistance.
To program a second remote control key for a 2000 Mercedes-Benz 500SL, you typically need to have the existing key on hand. Insert the existing key into the ignition and turn it to the "On" position without starting the engine. Within 10 seconds, insert the new key into the ignition and turn it to the "On" position as well. This process may vary, so it's recommended to consult the owner's manual or contact a Mercedes dealership for specific instructions related to your vehicle.

Look up your local MB dealer and phone them and as what documents you need to bring in to get a replacement key. If it is an infra red key they should be able to program it while you wait. Also you should be able to get the newer chrome trimmed key.

Take your key to a Mercedes Benz dealership with proof of ownership of the vehicle (the Title or Registration papers) and a picture I.D. (showing who you are) preferably your driver's license. They won't work on the smart key unless they know that you are the owner of the vehicle and can prove you are who you say you are.
