How To Fix A Trunk Latch

Fixing your trunk latch doesn't have to be costly or difficult if you follow some simple procedures. If the latch mechanism is corroded, or dirty, loosen it up by spraying it down with penetrating oil. As an added precaution, you may also spray lithium grease on it to keep it moving. Do not use any silicone spray, because it can get into your air cleaner, and possibly contaminate sensors there.

If the cable that leads back to the inside release mechanism is stretched or frayed, re-adjust it and try to find out what is causing the cable to stretch. Pulling too hard can cause things to be overstressed. If the cable feels grainy or gritty when you touch it, try lubricating it by using an aerosol spray lubricant. Do not use penetrating oil because that is too light and it won't get the job done. Make sure it has a straw like nozzle. Place one end of the straw up against the end of the casing containing the cable. Fold a clean rag over the junction of the straw and cable, and squeeze it tightly with your fingers. When you push on the nozzle of the aerosol can, the lubricant will be forced down between the cable and the casing it is in.

If you have an air compressor available, you can use a blast of air to force the lubricant deeper into the casing. This technique works for almost any type of cable found in vehicles today, including most heater-control cables. If the cable is showing corrosion or its steel threads are poking out, you need to replace it right away. There is no point in trying to fix it because it can snap at any moment. Lubricate the new one regularly to keep it in good working order. Prevention is the best maintenance you can practice.
