Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
The 1-year warranty from Behringer applies!
is supposedly a good number to talk to Behringer. Put in a failed-within-warranty claim on free repair, and ask where a Behringer repair facility is, and require an RMA #. That way you'll be able to have the keys repaired under warranty, I hope.
Perhaps the keys can be replaced / repaired. That is standard enough with any keyboard instrument of this sort that has a defective key or two.
Would you want to undertake such a replacement of keys yourself? or would you prefer to have that done for you by someone in your region?
If so, please tell me your local zip code, or town/city and state. Thanks.
Replacing keys is a matter of (summed up)
1. opening up the keyboard - in some cases, the outer case needs to be taken off. (In other cases, though, the individual keys can be remoted, exposing the keyswitches below them, without removal of the outer case at all. I'm not sure which type yours is yet...)
2. taking off the key (that your fingers touch when playing) from the whole keyboard.
3. assessing whether the keyboard is damaged inside, or whether the keyswitch (a sort of small button that the keys your fingers touch press on) is in need of replacing, or only the key parts above the keyswitch.
4. taking appropriate action.
But there is a step to try before those steps: taking compressed air and spraying into the cracks between the keys that aren't sounding and the adjacent keys. An air compressor of the sort used to fill tires can be used for this (provided it is used in a clean area and does not suck up dust and introduce it into the keyboard.)
Press down keys adjacent to the ones that don't sound, and with the compressor, spray air into the cracks between the depressed keys and the not-sounding key.
That sort of forced-air cleaning can revive a clogged keyswitch that has gotten dust or crumbs into it. (If it revives your keyboard, then a caution against ever eating anywhere near it, would be appropriate.)
Let me know what you think of this. Thanks.
I have found no sources whatever for dead Behringer keys or keyswitches. I'm sorry, really. But at least two reviews have had very unfavorable things to say about the Behringer out-of-warranty experience.
Casio and Yamaha are better names for electric/electronic pianos. Just to mention that in passing. And their provision for out-of-warranty repairs are better for sure.
As for your region and Behringer out-of-warranty repair servicing....
...what I find upon some searching is, pretty much nothing! I am astonished, even with the unfavorable accounts I have read already.
But if there are no parts available, then doubtless no one can advertise that they repair Behringer pianos.
I really am sorry to have these results and no others. This is very unusual... there's generally *something* that can be pointed to, or something that can be done. Not in this case, though.
Since, doubtfully, another Expert here might have more to find, or more to suggest (than just repeating what I have already said), in the way of Utah-based Behringer piano repair, or parts availability for such repair, I have Opted Out - with apologies.
