If you now have to stand next to the car before the fob works, the problem is usually simple and cheap.
The battery is first suspect
Fob batteries weaken gradually, so range shrinks over weeks before the fob stops working. Replacing the coin cell fixes most cases. Check the owner's manual for the battery type.
Worn buttons and damage
Drops and water can crack the circuit board or wear out the button contacts. If a fresh battery does not help, the fob may need repair or replacement.
Interference
Range can drop near radio towers, other electronics or a phone pressed against the fob. Try again in a different spot before assuming the fob is failing.
When to replace it
A replacement fob has to be programmed to your car. Key fob replacement and programming are available from Choice City Locksmith in Fort Collins, Berthoud and Severance.
