How to Use the Key to Remotely Start a BMW 5 Series?
2 Answers
To remotely start a BMW 5 Series using the traditional remote key, press the lock button three times consecutively. Below is additional information about remote starting: 1. Principle of Remote Starting: Remote starting a car involves using the remote key to start the engine or motor without the need for someone to enter the vehicle. It is a function that allows the vehicle to be started through remote control. The principle is that the key or a mobile phone sends a signal to remotely start the engine, and most models can be controlled via the car key. 2. Installation Conditions for Remote Starting: The remote start control system can only be installed in automatic transmission models. This is because automatic transmissions are equipped with a TCU (Transmission Control Unit), which communicates gear information to the ECU (Engine Control Unit). The engine will only start when the onboard computer confirms that the gear is in the P (Park) position. This is done to prevent the vehicle from moving unexpectedly. Aftermarket installations do not have this protective feature.
Using the key fob to remotely start the BMW 5 Series is something I do all the time—super convenient! The steps are actually very simple: After getting out of the car, first lock it with the key fob, then press and hold the lock button toward the car for about 3 to 5 seconds. You’ll know it worked when you hear the engine start or see the lights flash. This method is especially useful in winter, as it pre-warms the car and automatically turns on the AC to heat up the interior, so you’re comfortable as soon as you get in. I use it every day, especially in the mornings to save time—just make sure to do it in an open area, not a closed garage, to avoid any risks. If the key fob battery is weak or there’s signal interference, it might not work, so check the key regularly. The whole process takes just seconds—effortless and efficient. Highly recommended!
