Hundreds of Savannah home-owners will have to pay hundreds of dollars each to repair or replace garage door openers.
Problems started last week because of military upgrades.
Ft. Stewart officials say radio towers at Hunter Army Airfield are causing widespread disruptions to garage door openers.
Most home-owners reporting problems have older units using a specific frequency.
Base spokesman Ron Elliot says the upgrades are needed for 911, military police and other Army uses.
"There's really nothing that the military can do about it," Elliot says. "We are the authorized users of this band and we have no deviation from that."
The Federal Communications Commission gives priority to military uses in the frequency used by some older household products.
Larry Jameson of Savannah Overhead Door says people have been calling non-stop from zip codes 31401, 31405 and 31406.
"The only thing that the customers can do if they have an older unit then, of course, they would need to replace it," Jameson says.
Jameson says, fixes range from $180-$375.
Residents in other military communities nationwide have reported similar problems.
