Modern fobs come with rubber seals that keep out water. A splash of water or a light rain is acceptable however, submerging them in saltwater can damage the chip's electronic components.

The key fob contains an electronic chip that communicates with the immobilizer system of the vehicle to begin it. This system makes use of cryptocoding systems in newer vehicles and the older red key system used in older models. This chip will have to be replaced if it's faulty.

Faulty 12 Volt Battery

A defective battery can cause the remote to cease working. The car's computer will not recognize the remote if this occurs.

Before you replace the battery, test it using a an voltmeter for determining its capacity. A fully charged battery will read 12.6 volts. If the reading decreases significantly, it is time to replace the battery.

Put an electrical load for a short time on the battery to test its capacity. This will take away about 1% of the charge on the surface. After that, measure the voltage. The better the battery's capacity, the longer it can maintain its voltage. The ideal scenario is to keep it at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most typical reason for a keyfob that ceases to send signals to the car. The battery is able to be replaced to resolve this issue. It is important to buy an identical battery voltage and dimensions as the original.

Fobs aren't indestructible and are susceptible to damage. Contacts on batteries and buttons can be damaged through rough handling.

If your OBD2 scan tool isn't turning on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it's likely that a fuse has been blown. This is one of the most common causes of a scan tool failing. The simple fix is usually to replace the fuse that has been blown.
