Security light is blinking and the car won't start. I have done a search and know about getting my key checked out, maybe having to replace the lock cylinder and getting new keys, and the vats bypass. I have another issue related to this one. The alarm started going off and I couldn't get it to stop so I disconnected the battery. It's been over an hour and I went to connect the battery and the alarm is still going off. Any way to connect the battery back up and stop the alarm?

If I replace the lock cylinder and get new keys, do I have to go through a chevy dealer to get them?

If I do the vats bypass to see if that'll get the car running again, can I reverse it later with no issues?

Thanks in advance and I appreciate the help.

If you don't hack up the wiring, you can easily reverse the bypass.

Some searches bring up issues with the wiring from the lock cylinder going bad or coming loose. Will I have to replace the cylinder all together for this or would the bypass still work?

Also, my alarm is still going off everytime I reconnect the battery. Any way for me to get it to shut off?

The bypass is done under the steering column and negates (bypasses) the wiring to the key cylinder. I don't mess with or know anything about alarms.
