Key Fob Programming in Minneapolis, MN

Cold weather and car remotes

Key fobs run on small coin cells, and those can lose output in deep cold. Winter 2013–14 shows how long the cold can last: the Minnesota DNR had 53 Twin Cities days with a low at or below zero on its tally by March 3. A fob that unlocks the car from across a parking lot in October may need to be right at the door in January.

Before asking for programming, rule out the simple causes:

• Try a fresh battery of the size printed on the old one.
• Carry the fob in an inside pocket on cold days, not in a bag or on the dashboard.

If a new battery does not help, or the car shows a key-not-detected message, the fob may have lost its pairing or been damaged. That is when programming, or a new fob, comes in.

Garage fobs and car fobs

With 26.8 percent of Minneapolis homes in buildings of 50 or more units, a car may well sit in a shared garage. Keep the two kinds of fob apart: the building's garage or door fob belongs to the building's access system and is managed by the building, while your car fob is paired to the car. Programming a car fob will not fix a garage fob, and the reverse is also true.

Car fob programming happens at the car, so say where it is: a garage level, a driveway or the street. If the car is on the street during a Snow Emergency and the fob will not unlock it, add the day and which side it is parked on, since it may have to move.

What to have ready

• Every working fob and key for the car, because on some vehicles a fob left out of programming stops working afterward.
• The VIN, plus year, make and model.
• Any new fob you bought, with the part number or FCC ID from its back.
• What fails: the buttons, push-button start or both.
