Can you go into more detail as to what you mean by your "remote entry is now dead"? Are you referring to your remote key's functioning...or are you referring to the entire keyless entry part of your cars FBZV (central locking) system?

If you mean your remote key...does your other key work? If it does...have you tried reinitializing both keys?

If you mean your entire keyless entry system doesn't work...does the regular central locking system work (the interior central lock/unlock button on the center console, or using the key manually in the lock cylinders)...and if you do lock the vehicle manually with the key using the lock cylinder...when you walk around to the fuel filler door flap...does it lock or remain unlocked?
