A decent locksmith should have a frequency indicator. (it's about the size of a pocket calculator but twice as thick). All they do is press both bottons, one on the key and one on the indicator and it displays the frequency. (If you live in Brisbane the guys at Millennium Locksmith Wolloongabba has one).
The numbers don't mean squat. (I previously thought the same)
Replacing the battery also does squat. Gez we'd be shagged if we needed to program it everytime. It's amazing LR didn't try this....:D
