Most cars built after 1995 have keys with transponder chips in them.  This chip disarms the cars immobilizer using a radio frequency when starting the engine. The use of such keys drastically decreased the rate of car theft. But it also made it more difficult for car owners to get replacement keys unless you know the right people to call.  We can help when you’ve lost your keys, or locked them in the car, whether you have transponder keys or not!  Replacements are no problem so call us today.  We serve all of St. Charles county, all the way down to Chesterfield.
