Hi all, I think the answer to this thread and Brid's thread "Puma Owners: Non Start Issues" lies in the owners manual on pages 6 and 7. My one month old 110 will not lock or unlock with the second remote and I think I'll have to carry out the Emergency Key Access (EKA) procedure. Brid's initial thread appears to be exactly like a flat battery in the remote and this too has a specific procedure which has to be done whilst sitting in the vehicle and within 5 minutes of commencing or you have to carry out an EKA.
Hope this helps.....let me know how it goes.
David.
