Lost every Impreza key?
When your photo ID lines up with the registration or title, an Impreza with no working key is rebuilt from Subaru's key code record for its VIN. Chip cars have the lost key removed from the immobilizer before we go.
A 2005 to 2007 chip key comes to $199, a 2008 to 2011 car to $219 with the laser-cut key, a turn-key car from 2012 on to $239 with the remote head key, and a push-button Impreza to $319, which we confirm by VIN because newer cars add factory-alarm steps. Each of those includes the $60 no-key charge.
For an Impreza from the 1993 to 2004 model years, or a 2005 to 2007 car without a chip, there is nothing to program: we cut a plain key from the code. A found key would still turn that ignition, and locking it out for good means swapping the ignition cylinder for one cut to match the new key, $179 to $349.
