Transponders shetlan. While those keys can start some cars out there, however, many cannot be started with those try out keys. Transponders have now been out 23 years and are increasing greatly.

GM started VATS in 86 for the Camero. Later on (89-99ish) GM moved to Passkey I & II, which was very similar to VATS. These keys alone won't start a VATS or Passkey I & II system. So can rule out starting a number of GM cars from the 88-99ish period.

Next, GM moved on Passlock I & II. This is where GM took a step back and dropped the ball when it came to security. Passlock was designed to prevent only against force tools. Those try out keys will allow you to steal a vehicle equipped with Passlock.

Later GM released Passkey III, which is a transponder system. You can find these on 98-current cars on selected models. These keys will also not work alone to steal the vehicle with this system.

Now lets move to Ford/Lincon/Mercury

Ford/Lincon/Mercury started with PATS for the Mustang in 96 although it really didn't catch on until 99ish for most Ford models except their super duty trucks (F250 and higher), which caught on in 07 I believe. I know it was after 06.

Next we have Chrysler/Dodge/Jeep

They too started moving into transponders with their Sentry Key Ignition Module (SKIM) in 99ish.

Honda started with their system in 98 for the Accord.

Like I said shetlan, still many cars out there that you won't be starting with just those keys alone (although you can open them).

Here are some cars I can think of off the top of my head that can and cannot be stolen with those keys alone. Those keys can open many of these cars though.
