I need to disable or block the side key moni(monitor) so others can't hear on my private CTS DTS. I use a Baofeng UV-5R and a UV-82. Another team that uses the same repeater, but has different CTS DTS codes, can hear when I press the side key moni.
Baofeng uv-5r,uv-82. i need disable or block side key moni(monitor) for don´t listen private cts dts

$\begingroup$ Just don't press the button, then. And always remember that everybody can still hear your transmit, whether or not you use any kind of tones. $\endgroup$– SDsolarCommented May 24, 2017 at 20:57

Don't bother.
CTCSS tones are not an effective privacy mechanism. Anyone at all with a FM two-way radio or scanner can receive your transmissions; attempting to prevent this by locking down your radios gives you only the illusion of privacy.
(P.S. This site is for Amateur Radio, and I'm guessing you're actually a commercial radio user. I'm answering your question anyway because I think it's close enough to being about the technology in general and Baofeng radios are commonly used by amateur license holders as well.)

$\begingroup$ I totally agree with @Kevin, and would only add that the only way to disable it would be to take an X-acto knife and cut off the rubber part. But then there goes any kind of water resistance. So I echo: Don't bother. $\endgroup$– SDsolarCommented May 24, 2017 at 20:55

CTCSS tones or DTS digital tones, are only for "Receiving intended signals".
If a receiver is configured to receive on a frequency with CTCSS or DTS, then the squelch is only opening when the transmitted signal contains the "matching" CTCSS or DTS.
If a signal is transmitted without the "matching" CTCSS or DTS, then the receiver's squelch will not open, and you will not hear the signal.
However, if a receiver is configured on a frequency without CTCSS or DTS, then it will receive all signals, including those which have CTCSS or DTS, and the squelch will open.
So, if you are communicating on a frequency with many many users, you can transmit with CTCSS/DTS, and receive with the same CTCSS/DTS, and you will only hear these signals....
However, everyone else; with receivers configured without CTCSS/DTS... will also hear your transmitted signal!
This is why it is a "false/illusion of privacy" as answered already.
Use CTCSS/DTS only if you want to restrict a receiver to a specific transmitted signal, with the understanding that others can perfectly receive your signal.
HTH.
