When I bought my 3200GT some years ago, it came with the "all important" red key and a couple of black keys, however despite disarming the alarm, opening the doors and turning in the ignition, one of the black keys would not actualy start the car, the reason being that at some point, one of the previous owners must have lost / dropped the transponder when swapping the battery for the alarm. It always bugged me that one key was effectively useless so I eventualy decided to see if i could resolve it.
When new the 3200GT would have been supplied with 3 keys, the red master and 2 black user keys.
The red "master" key was not for normal use but instead for replacing keys, storing codes etc. quite often the owner would leave the red key with the supplying dealer for saf keeping.
The black keys comprised of 3 parts:
The cut blade which operated the physical locks - doors, boot and ignition.
The circuit board (with batteries) that armed / disarmed the alarm and operated the central locking.
The Transponder which disarms the immobiliser when the key is inserted in the ignition.
Quite often the transponder drops out of the key and lost when the key is opened in order to change the battery for the alarm / central locking which then renders the key useless as far as actually starting the car is concerned, this is clearly what had happened at some point to my spare key.
The transponder is a T5 type and can be purchased quite easily, at this point there are two options, if the key is already coded or you have coded it, the key will need to be added to the cars recognition system, please note that if you do this, all keys to be used should be included in the process which is descibed below>
To be honest I was not bothered about my keys having different identities (although some might say there is a benefit) and was happy to give the new transponder the same identity as the other key ie. clone it. I therefore ordered a new transponder and a transponder programming tool, if i am honest i wasn't really expecting this to work but decided that given the price of the transponder and tool compared to a replacement from Maserati it was worth a try!
When the tool and transponder arrived, I first tried reading the working key which gave information for the transponder within it, I made a note of this information and then removed the key from the tool, inserted the new transponder in the key which had been missing one, placed it in the tool and input the recorded information, the key needs to be placed properly in the tool but once it was I received a message saying the process was a success!
I then tried both keys in the ignition of the car and both now work as they should.
