I recently had the dealer reprogram my D1 remote, so probably not a direct comparison. They didn't need any numbers, but I imagine a D1 remote is a different beast from the LR3 part. If you have a non-functioning original LR3 remote that you are replacing then you might try opening up your remote, calling the service department, ask them what numbers they need, and look inside your remote to find these numbers so you know how to identify them. If you are not 100% sure the replacement will be a perfect match then get some guarantee that you can return it.
