What should I do if the Corolla remote control signal is weak?
2 Answers
The solution to weak signal in Corolla remote control is: replace the battery and check if there are any electronic devices around that may interfere with the remote key. The Corolla is a compact 4-door, 5-seater car under FAW Toyota. Taking the 2021 Corolla as an example, its body dimensions are: length 4635mm, width 1780mm, height 1455mm, wheelbase 2700mm, fuel tank capacity 50l, and trunk capacity 470l. The 2021 Corolla is equipped with a 1.2L 4-cylinder turbocharged engine, using direct injection fuel supply, matched with a 10-speed continuously variable transmission.
If the Corolla remote control signal is weak, I would first replace the battery. A weak key battery often causes this issue. You can buy a CR2032 button battery at the supermarket and replace it yourself to solve the problem. Additionally, it's recommended to test the button response in an open, interference-free environment, avoiding areas near signal towers or monitoring rooms. If the spare key also fails to connect, you might suspect an issue with the vehicle's receiver. If the key has been dropped or exposed to water, it could cause a short circuit in the internal wiring. Taking it to a professional repair shop to clean the contacts might fix the problem. Lastly, remember not to wrap the remote with a metal keychain, as signal interference is quite common. Replacing the battery is the most efficient solution, costing less than ten yuan to restore normal sensitivity.
