Honda ridgeline trunk lock not releasing with remote key after Honda dealership did some troubleshooting for a dead battery.

SOURCE: manual trunk release location

need to fold down back seat and pull the emergency cable located near the key hole

SOURCE: Battery Dead - Can't open the trunk to recharge battery. Help!

The 1994 xj6 sedan. The trunk should be opened by the key unless you have green keys only (valet keys).
If this is the case then open the hood and on the firewall there is a black plastic square box with a + sign on it, lift up the plastic cover, connect your jumper/charger on a low boost and this will give you enough power to push your remote trunk release switch.

Posotive can be found in hood driver side next to fuse box. It is a small rectangle box. You can hook negative to any solid ground on the car.

Check for broken wires running from the body to the trunk lid through the rubber boot.When the trunk is closing you can see the kink in the rubber boot.There are 11 wires to supply 1 solenoid so I think Chrysler knew there was problem.

Code can be found on a credit card like card found included in your owners manual kit. Follow instructions in owners manual on resetting code. Key position in ignition is critical for it to work as is the time it allows you to enter the code. If car was purchased used most Honda dealers will provide you with the number. Best of luck.
