This item is same as or equal to the devices that came with my SRX that I purchased used. One of the devices that came with my car was dirty/worn so I wanted a new one. According to the Cadillac forum some owners reported difficulty programming blank RKE devices. I was disappointed that no instructions were included with the RKE. I went to the vendor's website and I couldn't even find the item available for sale. Fortunately it programmed quickly and easily following the detailed instructions in the owners manual and I am very satisfied.I haven't tried to get the emergency key cut but I don't expect any issues with that.
This key was a fraction of the price and I programmed it myself using the car manual. Worked on the first try and done in less than 5 minutes! The key will need to be cut by a locksmith, but it still saved me hundreds of dollars!
