So my 99 is equipped with keyless entry. I found a new DEI/GM VSL-4000 alarm cheap. I'm trying to get some understanding of how the keyless entry works, etc. It looks like the keyless entry receiver runs to the BCM. The BCM then apparently sends the signals to the appropriate door lock/unlock relays. Can I disconnect the keyless entry module completely, then disconnect the output wires from the BCM to the lock/unlock relays and connect them to the new VSL4000 module? Or is the car going to spaz out on me because the BCM is missing these components?
