Why we can't copy car remote patterns?
Do car remote uses different type of radiation?


Yes.

TV remotes use infrared transmission. On many the LED is visible at the end of the remote. You can test the operation of an infrared LED using your camera phone as they are responsive in the infrared region.

Car remotes use one-way radio signalling.

How do they differ?


Infrared requires line of sight to the receiver or enough reflective surface to bounce the infrared light. Point the remote into your hand and the television will not respond.
Your car's remote control will work inside your pocket. This is the biggest clue that it is not using light as a transmission medium.


Your programmable remote control is for infrared remote only. It will not be able to receive radio signals from your car key.
