keyless entry module on 1999 eclipse

Anybody know how to disable the factory keyless entry?? The customer lost the factory transmitters in front of his house and doesn't want anybody to have access to his car.Thanksinstalling, one day at a time..

Thanks for the reply.I was installing a new clifford and the customer didn't want the factory keyless entry to work because he lost 1 of the remotes in front of his house.......I found the keyless entry module behind the driver side rear panel and cut the red power wire for it.I found out if you disconnect the keyless entry system completely,the driver door unlock won't work.Hope this helps someone else out.installing, one day at a time..
