That is great as long as you're not concerned about being able to set the alarm. But if you set the alarm with the factory key and lose it, and try to open it with the new key, you will send the BCM into Lockdown Mode. and your backup key will not be able to take it out of lockdown (because it cant disarm the alarm) Aka turning your car to a paper weight unless the BCM is replaced and new keys are made at dealership. This happened to me and it sucked. I have a write up on another post All about it.I just went through all that , dealer wanted 300.00 and no guarantee when new key would arrive. They come precut via VN#, Instead I went to locksmith, had my remote cloned and now have spare key without remote, It will open & lock doors manually and start vehicle. Total cost 55.00 and no waiting, did it on the spot.
