The key problem can be as simple as a mis-alignment of dust under the key. A lot of it depends upon how much you want to spend with the phone. Years ago I opened a 600 without a problem and fixed the problem. Another phone I opened up required major surgery so I put it back together and took it to the hospital. The tech there asked if it had been opened and I said yes, he said it violated the warranty and that was that.

A used phone presents a problem. With no warranty, repairs will not be cheap and if fixed, you still have a phone with no warranty. So in my case, since my devices have always been heavily used for work, a warrant of some type is very important and hence the reason I have stayed away from used phones related to work. I would opt for a new phone. There are companies out there that refurbish phones - a search would be required for that information. Palm repairs - that is an option and a phone call would probably answer that question.

Good luck. Ben
