What to Do When the Keyless Entry System Fails?

[JasperLee]

Solutions for keyless entry failure: If the issue is caused by a dead car key battery, simply replace it with a new coin cell battery. However, if this is not the reason, the only solution is to take the car to a 4S shop for inspection. Below are some tips for preserving smart keys: 1. Do not store them with electronic devices: Since smart keys use low-intensity radio waves, avoid placing them near electronic products or devices such as radios, TVs, computers, and microwaves. These are considered the 'nemesis' of smart keys. Electromagnetic waves not only drain the battery but can also interfere with the smart key's chip, eventually causing it to malfunction. 2. Avoid rough handling: Most smart keys have fragile internal circuits that can easily be damaged by strong impacts. Additionally, if a smart key gets wet, the internal circuits may short-circuit, leading to remote control failure. Also, avoid placing the smart key under the windshield or in high-temperature environments exposed to direct sunlight. 3. Do not keep the spare key in the car: Avoid storing the spare key inside the car or together with the smart key.
