What are the reasons why the trunk button of the 12th-generation Crown cannot open?

The reasons why the trunk of the Crown cannot open include: a short circuit in the trunk module of the battery, a blown fuse, a dead remote key, insufficient power, or a damaged trunk lock. Below is relevant information: Toyota Crown: The Crown is a mid-to-large-sized car brand under the Toyota Group, first launched in Japan on January 1, 1955, and has now exceeded the 13th generation. The domestic Crown engines come in three types: 2.5L, 3.0L, and 4.3L. The first two are designed with a V6 cylinder and 24 valves, while the 4.3L engine features a V8 cylinder. They are equipped with the Dual VVT-i system for intelligent variable timing on both intake and exhaust valves. Domestic Crown: The domestic new Crown comes in four models and seven grades, all powered by a 3.0L dual VVT-i engine, paired with a 6-speed automatic transmission, and built on the FR (front-engine, rear-wheel-drive) platform, combining smooth handling with ample driving power.
I've driven a 12th-generation Crown for over a decade, and the trunk button is the most prone to failure in older cars. The most common issue is oxidized button contacts causing poor connectivity, especially after water ingress during car washing which accelerates rusting. Wiring aging and breakage is another major problem - repeated trunk opening/closing causes wire harness wear and insulation damage. Blown fuses aren't uncommon either; I recently encountered a burnt 15A fuse in the fuse box. It could also be the trunk lock mechanism itself getting stuck, sometimes due to dried-up lubricant preventing rotation. Don't forget to check the key fob battery - weak remote signals can affect button operation too. Try using the spare key or interior switch first to rule out lock mechanism failure. These components are relatively complicated to disassemble - if you're unsure, better let the repair shop handle it.
