BYD F0 does not have a keyhole, and the engine can only be started with a one-button start. BYD F0 is a micro car under BYD, and all models of this car are equipped with a 1.0-liter naturally aspirated three-cylinder engine. Here are the extended details: 1. Body dimensions: The wheelbase of BYD F0 is 2340mm, and the length, width, and height are 3460mm, 1618mm, and 1465mm respectively. 2. 1.0-liter naturally aspirated three-cylinder engine: It has a maximum power of 68 horsepower and a maximum torque of 90 Nm. The engine's maximum power speed is 6000 rpm, and the maximum torque speed ranges from 4000 to 4500 rpm. This engine is equipped with multi-point electronic fuel injection technology and uses an aluminum alloy cylinder head and block.

I've been driving my BYD F0 for over three years and once encountered a situation where the remote key ran out of battery, which left me in a panic. Later, I discovered that the hidden keyhole is located on the exterior door handle on the driver's side. The small plastic cover can be easily pried open with a gentle lift. Once opened, you can see the keyhole. Insert the mechanical key that came with the car, give it a twist, and the door unlocks. It's quite convenient. I recommend carrying the mechanical key with you just in case to avoid being stuck outside late at night in an awkward situation. Also, remember not to force the cover open too hard, as it can easily scratch the car's paint. I learned this the hard way and ended up spending a few dozen yuan on a new cover.

The BYD F0's hidden keyhole design is quite practical, typically located beneath the plastic cover on the driver's side door handle. Prying open the cover is simple—just use your fingernail or the edge of the car key to gently lift it. Once the hole is exposed, you can use the mechanical key to unlock the door. This feature is mainly designed for situations when the remote key fails, such as when the battery dies or there's signal interference. I've repaired many cars and seen similar cases. It's advisable to check if the cover is stuck and to clean the keyhole periodically to prevent dust buildup. In emergencies, trying this method is much quicker than calling for repairs.

When I was a new driver, I couldn't figure out where the keyhole was on my BYD F0. Later, a friend demonstrated that it's hidden under the cover on the driver's door handle. Just gently pull the plastic cover to reveal the keyhole, then turn the key to unlock the door. It's simple and convenient, especially useful when the battery is dead. Now I always carry a mechanical key as a backup.
