Help: can't connect Apple Bluetooth Keyboard

[space-time]

I have a 2 year old Apple Bluetooth Keyboard and Apple Bluetooth mouse. I didn't use these in about a year. I just got a MacMini and before I try to pair these to a new Mini, I thought to make sure they have fresh batteries and work.

batteris in Mouse were dead (poor envelops, one was 0.8V and one was negative 1 mV). I am not sure if the one that was negative can be recovered. The keyboard still has some juice.

Anyway, I put 2 sets of Eneloop cells in both Mouse and KB. I managed to pair the mouse with my MBP, works fine. I can't connect the KB. MBP will see keyboard, but connection fails. OK, I tried wife's MBP. Same thing. Machine can see KB, connection fails.

I think I used this KB with an iPhone or iPad at some point. I tried both iPhone and iPad, they can't even see the KB.

What do I do now? I am out of ideas. The only thing left is to reboot my MBP back in 10.6.8 since I think this is how I used it some years ago.

As a side note: my iPhone can see a Bluetooth device called SYNC but I have no ice what that is. My 2 MBP on my desk and my iPad cannot see this SYNC device. I thought it could be a Ford but I don't see any Ford in my neighborhood. I just went outside to check. No Ford here.

Back to the Keyboard: is it possible the keyboard is still paired with something? is there a way to reset it?

EDIT: I removed SYNC from he phone and now it's gone for good, I think it was a rental car I had 3 months ago and forgot about it

the computer can even see the name of the keyboard, still does not connect

With Apple's wireless keyboards and trackpads, the trick is to press and hold the power button throughout the entire pairing process.

Every such problem I've ever had was due to the device being unwantedly paired with something else within range. Does this look helpful?

SOLVED. Typing on this keyboard right now.

What happened is I have another Mac Mini in the living room (my backup server and eventual media server) and I forgot about it. The keyboard was paired with it. I removed it and now I can connect just fine.

Thanks

Next question: if I unpaid the mouse and keyboard from this MBP and I boot up a new Mac Mini for the very first time, will it connect to the mouse and KB? or should I use a wired KB/mouse the first time?

Thanks

It should look for and find the wireless thingies if nothing's connected to it.

Yep. Great minds, right? Almost posted the same thing, but saw you two had it covered.
