December 1, 20214 yr Hi, I'm new here and this is my first post. I have an Opel Vectra C - 2005 Pre-Facelift. Down below is a statement I found on-line somewhere and I would like to know if anyone knows if this is true or not! I have only one key and have now bought a second key off of eBay the flip kind, which has electronics, chip and battery already installed. My question is to save money on the programming would this statement below work with my second key after being cut. Thanks, Peter Programming a Single Key A handful of manufacturers will allow you to program a single key, even if you don’t have a key that works. Keep in mind that you’ll still need to have the key cut to fit the ignition, which means you’ll need to provide proof of ownership to a locksmith. That said, the process is much simpler than programming a second or third key: Insert the key into the ignition, and turn it to the on position. Don’t turn on the engine, only the electronics. Leave the key in this position for 10 minutes and 30 seconds, and then turn it off. Turn the key back on, and wait for additional 10 minutes and 30 seconds before turning it off again. Repeat the process for a third time. Return the key to the on position, and it will program the key. Test your new key by turning on the ignition.
