Remote Key battery

What battery to use for my non-diamond 99 540i remote key? 3V lithium CR2032 or 2016?
Any brand that I should stick to?

Thanks

CR2016, says so on the back of the battery when you open it up. ANY brand will do.

I see the OP received a good answer.

In addition, if the OP would like DIYs and further ideas and references, the following, from the bestlinks, should be good reading:

- The truth about the BMW diamond key transponder (1) and proper initializing (1) (2) and the truth about the 10-key limit to programming your own keys at home (1) & opening, charging, recoding, & battery replacement (1) of the new-style diamond key (1) (2) (3) (4) (5) (6) & converting the old-style 1996-2000 "square" key to a diamond key (1) & how to replace the rubber key pads in the old style keys (1) (2) & what to do if your key is locked inside your car (1) & a description of the various types of BMW "Remote", "Illuminated", "Spare/Wallet", & "Valet/Service" keys (1) (2).

This should be generally useful for the square key battery description.

This is potentially useful information from a thread today:

Any power supply that has 3 Volts nominal will be fine for the key. However, in the three cases of key repair I have done, the problem was always the battery prongs losing contact with the board. The battery is heavy and eventually breaks free. I resoldered them and put a bit of padding on top. If you need to change the battery, reuse the prongs. Ask the battery shop to point solder them on the new battery for you.
