The module is dead. The transponders in the key are a totally different system than the security system and remote keyless entry, but they both report to the same module. Both systems have failed, pointing to a dead module. There is no way you could reprogram the keys without a scan tool even if the module was alive-you need two fully functional programmed keys to program more. There is no way you can fix this car without a dealer's scan tool and most likely a new module.
