If your security ID badge has expired than you will need to go through the entire security badging process again. Fingerprinting, testing and background checks. A few weeks of you not being able to work. Sorry but if your badge has expired and you employer is not aware you better tell then asap... you have most likely just lost your job.
If your id is CO driver's license, go to driver's license office and start process for a new one. They will punch "VOID" into old license and issue you a paper temporary license with no picture. Take voided id, temporary license and another picture id. Also try calling TSA or airport security for ideas how to handle this. Faced same issue in 2005.
You won't make it through security.
