The alarm system is a Meta. Yes you can get a new fob. According to my notes from when I had a Coupe this is what is.
Alarm is Meta M99/11Amykro TFA
Alarm remote is Meta M100RC

CANCELLING EXISTING TX AND INTRODUCING NEW/REPLACEMENT TX
On receiving your new/replacement transmitter, follow procedure below.
1. To introduce a new TX at least ONE of the original TX's must be
functioning correctly.
2. Using a valid TX, carry out a series of 16 activation (deactivations one
after another) with less than 8 seconds between each activation.
3. After the 16 successive activation/deactivations the system will cease
arming/disarming. At this point, the unit has been cleared of all other
TX memories EXCEPT the one used for the 16 successive operations.
4. WITHIN 8 SECONDS activate any other TX's required to operate the system.
(If the TX is slightly out of synchronisation it may need to be operated
twice). The control unit signals TX acceptance by changing status (from
arm to disarm or vice versa) ONLY ONCE, after which it stops responding
to that particular TX. At this point the TX just used has been added to
the list of accepted TX's.
5. Repeat step 4 for each additional TX required.
6. When you have finished introducing all the other TX's required, allow at
least 8 seconds to elapse. From this moment all and ONLY the TX's that
have just been operated during steps 2 and 4 will operate the system.
ALL OTHER memories/TX's will be deleted.
NOTE: On instigating this procedure, only the TX used in step 2 and the
TX's used in step 4 will operate the system. Therefore, you must
ensure that you have ALL the TX's required to operate the system at
hand BEFORE step 2 is completed. This includes any ORIGINAL TX STILL
REQUIRED TO OPERATE THE SYSTEM.
For security and programming reasons, please record and keep all
transmitter codes.
