Just like our car keys, we have developed from the most original mechanical keys to remote control keys to smart keys with high penetration rate.

In addition, when using the smart key, try not to throw it away, because most smart key shells are relatively strong, but frequent throwing will cause poor internal battery contact.

The materials for making the key bai are mainly copper, zinc, aluminum, iron and other metals.

If you have strong hands-on ability, you can buy a key case online and replace the car key shell yourself.

At present, the car keys of common models are generally divided into three types: mechanical keys, remote control keys, and chip keys.

Look for a repair shop or unlocking company: ask a professional person to do professional work, and unlock the lock in about 5 minutes.
