oem honda single door genuine lock assembly is about Rs 4000. from Nasir Motors karachi plaza market.
these black central locking units used to cost Rs 400 back in 2010 for a complete set of 4 actuators, wiring fitting etc everything. i think they cost about 1000 now for a complete set.
i have several of these chinese ones, used them in my charade, civic, robotics projects. they never go bad because i put them in a ziplock bag with only the tip poking out. and seal every hole with glue gun.
the set installed in my ek civic is at least 2 years old now and still working.
