Short answer is Yes BUT READ carefully below (the instructions MES gives for programming keys) and you will need the vehicle security code as well.

This procedure allows the programming of keys/transponders in the Body Computer. The keys/transponders have to be pre-programmed with body computer's secret codes in order to be recognized by the vehicle. Follow the instructions on screen and make sure you have ALL keys (up to 8) before starting the procedure.
WARNING: DO NOT RUN this procedure if you don't know what you are doing as this procedure may permanently disable your keys! Make sure YOU HAVE ALL KEYS as you will have to program ALL of them into the Body Computer.
WARNING: You will also need to enter the electronic key code of your vehicle in order to execute this function. You can find this code on your vehicle's CODE CARD. Please be careful and note that the Body Computer will block itself for 30 minutes after an incorrect code is entered 3 times.
NOTE: You may run this procedure in simulation mode to see how it works. Basically, you have to do the following:
1. Start the procedure
2. The system will ask you to insert KEY 1 and click Y. After that the system will confirm if the recognition of the key is successfull.
3. The system will ask you to insert KEY 2. So, you have to remove KEY 1 and insert KEY 2. This procedure can be repeated for up to 8 keys.
4. The system will finally store all recognized keys into the body computer and will display a status of the whole procedure. You will still have a chance to abort the procedure before step 4 and restore the key data. However, after step 4 the new keys will be stored permanently and ANY existing keys that are not inserted/recognized during the procedure will be PERMANENTLY disabled in the body computer and it will not be possible to use them anymore.
ALSO NOTE: The vehicle will probably display immobilizer/key errors on the dashboard during the procedure! This is normal!
After the procedure:
1. Remove all keys, disconnect the OBD cable and wait 60 seconds
2. Take one key and start the engine with it
3. Turn off the engine and remove key
4. Close all doors and test the remote control (if this is an RF key).
Repeat steps 2, 3 and 4 for all keys!
