keyless go not recognised on one key but works on another

[toby_tobias]

One of my keyless go keys, the three button plastic key with the slim metal key inside has stopped working as a keyless go key. all the buttons work fine but the key brings up a key not recognised warning on the dash. when keyless go function used

the other key works fine and all the buttons on door handles work.

I am guessing it's a trip to a star garage to reprogram the key to the car, am I right??

It hasn't been dropped or abused.

he MB dealers have a special little box that they use with STAR to re program the keys,,this takes about ½ an hour to do
