What to Do When the Highlander Trunk Won't Open?
3 Answers
The solutions for a Highlander trunk that won't open are: 1. If it's a cable-operated mechanism, check if anything is blocking the cable or the trunk lid; 2. If it's electric, press the switch and listen for any sound from the linear motor or unlocking solenoid, check the power supply, and see if the fuse is blown. Trunk maintenance methods: 1. When cleaning, use a brush to remove dirt, including the edges and troughs of the trunk, and perform odor treatment after cleaning; 2. Use separate bags to organize items systematically; 3. Lay a trunk mat to prevent dirt or liquids from entering and eroding the trunk surface, while also preventing items inside from sliding, reducing the risk of contamination or damage.
I've driven a Highlander for over a decade, and the trunk not opening is really not uncommon. That time when the whole family was on a trip, I pressed the remote but got no response, and I was so anxious. It turned out to be a dead remote battery, and replacing it with a CR2035 did the trick. If the power tailgate fails, try restarting the vehicle first; there's usually a small hole under the trunk lid where you can insert the key and twist it to manually unlock—don't force it open to avoid damaging the lock. It could also be a blown fuse; check the related fuse in the engine compartment's fuse box, and replacing it costs just a few bucks. Regularly clean the lock slot to prevent dust buildup from causing jams. If all else fails, head to the 4S shop—they're more professional at diagnosing wiring issues. Safety first; don't delay and risk damaging the system.
People with some knowledge of cars say there are several common reasons why the Highlander's trunk won't open. Issues with the electric control system may be due to sensor failure or circuit shorting; restarting the vehicle usually fixes this. Or the remote battery might be low—replacing it with a new CR2032 could solve the problem; check if all doors are fully closed, otherwise the signal may be weak. The mechanical part could be stuck; try lightly spraying some WD-40 for lubrication. If a fuse is blown, check the fuse box for the trunk label and replace it. A reminder: remove any items inside that might be blocking the lock. For prevention, regularly maintain the locking mechanism to reduce such failures. Simple issues can be handled yourself, but for complex circuits, seeking professional help is the safest approach.
