I have a Kenwood TK-2160 and I am unable to

Based on the information you provided, it seems like the Kenwood TK-2000 radios you have may have been programmed with the wrong band split. The TK-2000 is available in both VHF and UHF frequency ranges, and it's possible that the radios you have are actually UHF models, despite being listed as VHF frequencies when you read the radios.
To check if your radios are UHF or VHF, look for a label on the back of the radio that specifies the frequency range. If it says UHF, then the radios can only accept frequencies in the 400-440 MHz range. If it says VHF, then the radios should be able to accept frequencies in the VHF frequency range.
If you've confirmed that the radios are indeed VHF models, then it's possible that the band split settings may need to be adjusted in the programming software to match the specific VHF frequencies you're trying to program. I recommend checking the manual for your programming software to ensure that you have selected the correct band split settings before programming the radios. If you're still having issues, it may be helpful to contact Kenwood customer support for further assistance.

Do you indeed!

No problem, it is $76.00.

Change the EEPROM of a working same model Radio or put this EEPROM in any other Radio and see the result, if result is same then change EEPROM.

Also this indication is due to you put out of range frequency, check you frequency, it must be with Radio operating band.

To change the channel frequencies on your TK2100, simply press and hold the PTT switch ("talk button") and Monitor key, then turn the power on. Now press the PTT switch again. The light should change from orange to red and a beep should sound. Next, adjust the channel switch to the channel you wish to program. Now simply press the PTT button to choose between 4 to 8 possible frequencies, depending on your model.

If I am not mistaken the TK 768 can only operate in a channel based manner as it is a land mobile radio, not a ham radio. The TK line is Kenwoods Land Mobile ( commercial trucks, taxi cabs and so on) line. these radios are meant to be operated on specific frequencies that are limited and assigned by the FCC . While the can be reprogrammed for ham radio frequencies legally, being designed for land mobile use, they are limited to the single fequency/frequency pair programmed into the channelized set up they use.

The TK-360 is an 8-channel commercial/business radio that's available with a wide variety programmed frequencies, and operation requires a license. Unlicensed operation could interfere with authorized users and carry a heavy fine/penalty. The MONITOR switch lets you lock onto and listen to one of the programmed frequencies even when you have not specifically been called. You can identify the programmed frequencies by using a frequency counter or a scanner with the "Close Call" feature.

I wasn't able to find a manual, but was able to find programming instructions online. I hope this helps!

The Kenwood TK-3200LU15 is the 2Watt replacment model for the TK-3101. the TK-3202 or TK-3203 are 4 watt models that can be used. Although, they have to be programmed with the frequencies and codes you are using. The TK3101 came with defualt GMRS/FRS frequencies.
