My trunk lid will not open on my 2005 nissan sentra. The remote not opening (do hear it click) and the inside button and key not working to open the trunk either

Hi, I'm not sure, but check and see if the back seats lay down. That if you can get inside the car of course.

I have a 2003 Nissan Sentra and have had this problem myself. When you operate the slide switch that is left of the steering wheel on the dash or push the trunk button on your key fob, can you hear the solenoid click, but the truck doesn't open? If it does, open the truck with your key and raise the lid. I found that the lever assembly in the bottom lock was hanging up. I lubricated with WD-40 and using a small screw driver I moved the levers until they moved smoothly. Then activated the key fob switch and it started operating. If the solenoid doesn't work then there probably is an electrical problem. Let me know.

may be manual release behind or under back seat and if not you may need to remove back seat and panal which should let you into trunk. once in there should be a release on the trunk inside to open it. most new cars have them to prevent someone from getting locked in trunk. after opened you may want to have lock system replaced or it could simply just need oiled....... hope this helps and good luck

Check for alarm system settings.,maybe its needs to be re -set. lubricate lock mechanism to prevent jams.

does the key turn the trunk lock?if not theres one issue right there.the other may be that the valet lever on trunk latch assy. may have inadvertantly been engaged if deck lid was slammed closed.the release solenoid will make noise when activated by fob or lever in car but because of valet being engaged cannot release latch.does key unlock glovebox?if not this may also be a valet key cut.contact nissan dealer to cut regular key.ive seen the slamming the deck lid scenario a million times as the valet lever takes hardly any effort to engage.good luck and let me know how you make out.

fold down back seat and manually release the latch them inspect lock for trunk

Sounds like the trunk latch actuator is out.

put some oil in barrel of lock ,if this doesnt work after a day of soaking then go through back seat open boot and lubricate everything in sight and behind the panelling

inside the trunk near the latch is a switch that kills the trunk remote

I believe you can remove the back seat and get into it. Remove the lower part of the back seat first and remove attaching bolts/screws to remove the upper part of the seat.
