What are the effects of a car key getting wet?

[SamanthaMarie]

The car key does not have waterproof function, so if the key falls into water or gets wet, it is necessary to deal with it in time to prevent damage caused by corrosion and oxidation of the internal circuit board due to prolonged exposure to water. The following are the methods to deal with a wet car key: 1. First, pull out the mechanical key of the remote key, then turn the logo of the key upward and pry open the back cover of the key. 2. Remove the key battery first to prevent short circuit of the internal circuit board due to the key being powered. 3. Remove the entire back cover of the key, take out the circuit board, use a paper towel to absorb the moisture on the circuit board and the front and back covers of the key, and then use a hot air blower to dry the circuit board and the key cover to prevent oxidation of the circuit board. 4. After completing the work of dealing with the wet key, install it in the reverse order of disassembly to reset it.
