It is unlikely that a short range GPS jammer in one car would cause 
enough interference to disable a wireless smart key in another. GPS 
operates on a much higher frequency than a car remote. Of course as most 
such jammers are illegal and obtained illicitly, they may not be very 
well made and so cause interference to more than just GPS.

Apart from location, GPS is also widely used as an accurate timing 
signal, including by some wireless networks. So jamming GPS could cause 
problems for some communications systems, particularly mobile phone 
networks.

ps: If worried about being trapped in a car, carry an escape tool. This 
is a small pointed steel probe, which can break the toughened glass of a 
car side window (not the laminated windscreen). There are pocket size 
versions which can be carried on a keyring and larger units which look 
like a plastic hammer, to keep in the car. These usually also include a 
seatbelt cutter. I purchased a glow in the dark model:
