What is the range of a car remote?
Keyless remotes contain a short-range radio transmitter, and must be within a certain range, usually 5–20 meters, of the car to work. When a button is pushed, it sends a coded signal by radio waves to a receiver unit in the car, which locks or unlocks the door.
What is the range for a remote car starter?
The remote engine starter can be effectively operated up to 80 feet in an open space. The physical makeup of the surrounding environment (hills, trees, buildings, etc.) may affect the remote engine starter’s maximum range.
Do RF remotes work through walls?
RF remotes use specific radio frequencies, typically a license-free 2.4 GHz bandwidth, to transmit a signal to a receiving device. The signals are able to be sent through objects like walls and furniture, extending the remote’s range.

Do you hold the car remote to your head?
My car’s keyless entry remote, for lack of a better word, sucks. I practically have to be next to the car to get it to work. Alas, plenty of the aforementioned people have given me the tip to hold the remote to my chin with my mouth slightly open to increase the range of the remote signal.
Why does your head affect the reception of a radio?
It’s also possible, by virtue of your head’s lower conductivity compared to copper, that it’s a less effective antenna. It’s also possible your head will act as a reflector, directing more of the radio’s energy at the car. It’s also possible your head will refract the waves away from the car.
Why does a remote car key not work?
Effective antennas (ignoring fractal antennas) typically have a length of λ 2 = 1 2 m ≈ 1.5 ft. So, the effect is probably caused by one or more of the cavities in your body (maybe your head or chest cavity) acting as a resonance chamber for the RF signal from your wireless remote.
What’s the best way to use a car remote?
If you aren’t willing to hold it to your head, pointing it at the vehicle seems to work better than pointing it up, and there doesn’t seem to be much dependence on how high you hold it. Finally, holding the remote to your chest is worse than just holding it at arm’s length.
