Question about Kenwood KDC-MP4028 CD Player

25 Answers

Forgot my code.

I connected the stereo in my car about a year ago and I put a code on it, now that I want to change the stereo into my pick up, it is asking for the code and I cant remeber it. I tried many but I can't seem to get the right one.Would any one know if I could reset the code and how?

    Same problem, but the model is KDC-7155. We bought the vehicle used, and all we see is "Enter Code". We've pulled the receiver out, but the serial numbers are only 9 digits long.

    The Embassy mechanic, while changing the oil, disconnected the battery and now we need the codes to make the radio work. Our car (Honda CRV) was Made in Japan and purchased here in Antananarivo, Madagascar. The radio is labeled a Matsushita Electric Industrial Co., Ltd. Osaka Japan - Model No. 39100-S9A-W200. REF.No. CQ-EH8484A Serial No. 10000721

    We have spoken with Honda reps in Japan, America and Canada and despite our having All paper work concerning the vehicle their position was,"Sorry, but we can not help you." There are a couple of websites that supposedly will send you the radio codes for your particular radio if you send them money. Sounds good, but, because of the extremely high credit card fraud in parts of Africa the security here at the Embassy STRONGLY urges against such activity if you have any doubts or concerns it may be bogus. So, we have been without the radio for six months now and are about to purchase a new one except this country doesn't seem to have ever heard of an in-dash 6CD changer with a radio! Go figure. If you can help my wife and I we would appreciate it beyond measure.

    Thanks,

    Mike

    I brought my boat used and when I changed the battery it is requesting a security code.  the dealer does not have a code.  Kenwood is no help.  They want me to remove the radio and drive it 50 miles to a repair station and then pay $60.00 to get it fixed.

How do I Reset a Kenwood Security Code? Kenwood car stereos are protected against theft by four digit security codes. If a thief steals a Kenwood car stereo, they will not be able to use the stereo until they enter the secret for digit security code. Unfortunately, many legitimate owners are also locked out of their Kenwood car stereos due to these security codes. This typically happens to people who buy used cars from people who forget to share the security code. However, it also happens to people who simply forget their security codes after several years. 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 the "Auto" button and "Track up" 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. 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 HOPE THIS HELPS!!!!! -- AMPMAN--

Lost radio codes


Not familar with your car but I had same problem many years ago with a Vauxhall Astra and did same as you, disconnected battery and re-connected, radio didn't work - but my display kept flashing for security code to be re-input, which I didn't have.
Yours could be the same if radio not worked since disconnection - solution: if you dont have code & not in any documentation you got with car, then the radio will need to be re-coded by a dealer (expensive) or enquire with local car spares shops - they normally know a cheaper source. Mine cost about £18 (5 years ago) to get re-coded & I had to remove & reinstall myself.

Trouble with car stereo


Hoang00, to change the time on JVC's i believe you hold down "source" for a while and a menu pops up.
SSwaim, sounds like a grounding problem. Check the connections behind the dash, possibly a couple came loose. I would say possibly a bad car battery but the headlights thing points to a grounding issue to me.
