Here is a typical procedure:. Given a bit code, four transmitters and up to levels of look-ahead in the pseudo-random number generator to avoid desynchronization, there is a one-in-a-billion chance of your transmitter opening another car's doors.
When you take into account the fact that all car manufacturers use different systems and that the newest systems use many more bits, you can see that it is nearly impossible for any given key fob to open any other car door. You can also see that code capturing will not work with a rolling code transmitter like this.
Older garage door transmitters sent the same 8-bit code based on the pattern set on the DIP switches. Someone could capture the code with a radio scanner and easily re-transmit it to open the door. With a rolling code, capturing the transmission is useless. There is no way to predict which random number the transmitter and receiver have chosen to use as the next code, so re-transmitting the captured code has no effect.
With trillions of possibilities, there is also no way to scan through all the codes because it would take years to do that. Sign up for our Newsletter! Mobile Newsletter banner close.

Keyless car door locks are becoming the new normal, serving as a replacement to the previously standard remote unlocking systems. We will soon forget the time when we still fumbled with keychains and operated keys. Modern systems can unlock one or multiple doors and feature remote start. One day, our cars will probably collect us and take us to our destinations without any human intervention, at all. No, in the interest of safety, the engine keeps running and the car can still be driven when the key goes out of range.
This is a necessary safety precaution, so you're not stranded or the engine dies suddenly if the key's battery goes flat while you are driving.
So, the key gives you keyless access and engine starting, but is not needed for continued operation. However, once the engine is shut off, it cannot be restarted without the functioning key in range. Based on most studies, no. In fact, some of these systems have been hacked, but most have been updated to be at least as secure as traditional systems. Each keyless system has its way to alert you that your key is in the trunk and will allow you to open it to retrieve it. In most places, it is not a critical feature or expected in normal cars yet, unlike air-conditioning and ABS brakes.
