You're in luck!

Click here, it will bring to a Tip page authored by one of our best technicians (Robotek). He outlines the procedure for clearing the codes on most Kenwood models.

If this gets you going, don't forget to give Robotek a nice rating as a thank you. I wouldn't mind one either!

Remember: Good things come to those who Rate!!

I have lost the security code for my kenwood cd receiver. The model is KDC-MP4033S. Serial number is KE1202U0900623.


Hi,

Unfortunately Kenwood Radios can only be decoded on a bench and must be connected directly to specialist software. They cannot be decoded via serial alone. There is however a special procedure that can be used to bypass the security on these units using a master code 5227 (KCAR) which I will outline below.

I have a kenwood dnx5120 and I lost power to it now when comes on it asks for a 4 digit code. What is this code. How can I gey past it. The stereo was in the car when I bought it.


The following is per Kenwood:

Q: How do I reset my security code?

A: If you do not know the security code for your unit, you will need to take the unit to a Kenwood authorized service center to have it decoded. The code feature can only be activated when the code has been entered twice, so it isn't accidentally activated. The service center will often require you to provide a proof of purchase as this feature is designed for theft prevention and the proof of purchase will ensure you are the rightful owner of the product.

I reset my deck now its asking for unlock code wich i dont have can you help


You can enter a 4-digit security code as an option after purchase of the unit. If you do so, make sure it is noted down somewhere. If you did select a code (or the previous owner has done so) this must be used when the unit is removed from the vehicle, or the constant power source is disconnected from the unit. When constant power is restored to the unit, the security code must be entered before the unit becomes operational. If the code is lost or forgotten I am afraid the unit has to be re-coded by a Kenwood dealer.
Hope this helps, Good luck with it.

Need security codes for kenwood KDC 4020


Common Kenwood Security Codes
Many Kenwood radios are configured with the same security codes:

KCAR - This seems to be a "backdoor" to some Kenwood models.
3051 - This is the security code which is printed in the manual of many Kenwood models.
1234 - This is a security code commonly chosen by Kenwood owners.
Entering Your Kenwood Security Code
If the car battery fails or is disconnected, the Kenwood will ask for the security code.

The procedure to enter your security code differs on various models of Kenwood car stereos. Here are three of the more common procedures:

Type 1
During the code request mode, while holding the DISP key depressed, press and hold the Volume UP or DOWN key for 3 seconds until the "..." display disappears.
Enter the security code using your Kenwood remote.
Type 2
Press and hold the "Auto" button and "Track up" (next track button on the right) on the face of radio at the same time until the four dash lines disappear.
Enter the security code using your Kenwood remote.
Type 3: Model# DPX-4020 and DPX-4030
Press and hold the 1 then the 6 preset keys until the display shows the letter 'C'.
Enter the security code using your Kenwood remote.
Entering Letters on your Kenwood Remote
To enter a letter using your Kenwood remote, press a button once for the first letter, twice for the second letter, and three times for the third letter -- then press the Track Up or Next Track key to send the letter.

To send the letter 'A', press the 2 key once and then press the Track Up key. To send the letter 'B', press the 2 key twice and then press the Track up key.

Finally, when you are done entering all of the letters, press and hold the Track Up button for 3 seconds.

The key sequence to enter the security code KCAR is:

5
5
Track Up
2
2
2
Track Up
2
Track Up
7
7
Track Up
Your Kenwood should then enter tuner mode.

A Security Code Bug in some Kenwoods
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.

i hope this works for you.

I lost my code to my kenwood radio how do i unlock it


Hi John,
This sure does happen a lot.
Get serial # Call Kenwwod Customer service,
They will either have you send it in to reprogram the PROM
Or ask you for proof of purchase to give you the code.

If you have no receipt, and you or someone else didn't acquire it late at night in a inappropriate way, tell them it was a gift, that's not immoral, I buy myself gifts all the time : )
Regards, Paul
