How to Unlock a Car?

First, adjust the steering wheel to your preferred position. Hold the lock with your left hand and grip the lock handle with your right hand, then rotate it clockwise until the lock snaps into place securely. If you need to unlock it, simply insert the key and reverse the operation.
My most common method is using the remote key fob to unlock: simply press the unlock button on the key, and you can open the door when within 1 meter. If there's no response, try the spare key or the physical keyhole—some cars hide the keyhole under the door handle cover; just insert the mechanical key and turn it counterclockwise by 45 degrees. Don’t panic if the remote fails—first try replacing the battery, as it’s often just a drained coin cell. Always keep spare batteries in the car to avoid being stranded in a rainy parking lot.
Last week, my neighbor couldn’t open his old Passat with the mechanical key and asked for my help. It turned out the door lock cylinder was frozen. I used a hairdryer to blow warm air into the keyhole for 30 seconds, then inserted the key—a click sound meant it was unlocked. I taught him to drip two drops of rust remover into the trunk keyhole to prevent rust. With the mechanical key, you need to insert it fully, then slightly pull it back half a centimeter before turning—older car lock cylinders wear out and require this angle adjustment. This trick is especially useful in winter. Northern friends should keep a bottle of WD-40 handy—it’s a lifesaver.
I never need to take out a key when driving my Tesla Model 3. Just connect your phone via Bluetooth in advance, and it automatically senses and unlocks as you approach the car; for the physical card key, simply tap it against the B-pillar sensor area. Nowadays, many domestic cars also feature this keyless entry system, like NIO where a light press on the door handle button automatically pops it open. If you forget your device, you can still unlock the car remotely using the app. This level of smart technology is truly hassle-free—no more fumbling for keys in the rain while carrying a bunch of stuff.
