rear hatch lock

[Ccube]

Has anyone tried to replace the lock core on the rear hatch of a basecamp? haven't seen any threads addressing that. replacing the side door lock with a digital lock seems pretty straightforward but is useless if rear door lock is not also replaced. Haven't spotted any complete replacement mechanisms on line so was wondering about replacing only the lock core. was able to pull mechanism easily but core removal is not obvious. thanks for any assistance.

I would suggest taking the lock mechanism to a locksmith. Some locks require special tools.
