An owner can ascertain whether a car has keyless entry by giving the vehicle identification number to a dealer. The dealer can look up the car and provide the information regarding remote keyless entry.
As of 2014, keyless entry has become a standard feature for most automobiles. With keyless entry, a fob on the key chain allows the driver to press a button to unlock the car and sometimes the trunk as well. Most keyless remotes also include a panic button that sets off the car's alarm and lights in case of an emergency. Not every type of remote works with every make of car, however.
