This is the only way to clear the code. You must have the remote to do this, it will not work without the remote. I work at an authorized Kenwood service center and tell you for certain that this is the only way it can be done. If you do not have a remote, you will either need to buy one or borrow one from somebody else who has a Kenwood radio. Most all Kenwood car stereo remotes will work, it does not need to be from the same model number but it must be a Kenwood car stereo remote. If you can not find a remote for this then you will need to take the radio to an authorized Kenwood service center and they will usually do it for a small fee.
The first step is the only part of this procedure that you do not use the remote.
1. During code request mode, press the Track UP key for at
least 3 seconds while holding down the AUTO key. (– – – –

the Track Up key. (Enters a “C” )
• Press the remote controller 2 key once, and press the Track

Up key. (Enters an “R” )

Many Kenwood radios are configured with the same security codes:
There is a reported bug in the security code handling of some Kenwood stereos. In models with thie bug, the security code is stored incorrectly. The workaround is to enter the wrong security code.
In models with this bug, you have to decrement the third character of the security code by one. If your security code was 1111, you would enter your security code as 1101. If your security code was 9999, you would enter 9989.
Finding the Kenwood Security Code
There are backdoor codes for each Kenwood car stereo, based upon the model and the serial numbers.
These backdoor codes are closely held secrets. Outfits like Car Audio Accessories UK will sell you the code for your radio for £20.
Sending your RadioBack to Kenwood
If all else fails, you can send your stereo back to Kenwood to have the security code reset.
