How to unlock my car stereo

the esn is only active if the previous owner activated it. the user would of used a CD to be a key cd and that is how they are unlocked. if the cd is lost or damaged, Eclipse can give a code to unlock it. However the original owner needs to have registered the deck with eclipse and have some kind of ID like mother maiden name. there is also a second registration that can be done. which an eclipse dealer can do, it is for used cars with eclipse radios, and things like that.
They can be real strict sometimes about giving out a code, and the authorized dealer has to be the one calling, and somtime that means a lot of time on hold.

These units do not have a security code like some radios. Instead, they are coded using a CD. You insert a CD into the radio and it codes to that disc. You need that same CD if you ever want to unlock the player. If you don't have it, you are SOL. Eclipse is no longer in business and they were the only ones that could reset it. The system is known as "ESN Security".

ESN Security: This unit is equipped with the Eclipse Security Network. You can register a particular music CD as a "key" device which unlocks the security. If the registered CD is not detected, the navigation and audio functions will be disabled when the main unit is disconnected from and reconnected to the vehicle's battery.

All Eclipse brand radios have a feature called ESN (Eclipse Security Network) installed. This means a Key CD may be inserted into the head unit so that if the unit is stolen or battey is disconnected from the unit you will have to enter the key CD to unlock the unit.


For example, lets say you purchased this unit from bestbuy. You installed it in your car and you wanted to activate the ESN security feature. You need to choose anyone of your cd's from your collection, lets say you chose The Offsping, Conspiracy of One. Input the disc hit the correct buttons ( I'll explain those later) and your Eclipse 54400's ESN is active.


Now, your 54400 is stolen a week later, the thief will plug in the 54400 into his car and it will show SEC [disc], so he/she will insert a cd and it will say [ERR]. If he or she does this 5 times it will show [call 800] which will lead them to Eclipse customer service, but you will have already called eclipse and told them that your unit was stolen. Whether you get your head unit back is highly doubtful but nobody else will be able to use it.


Now for your answer, to activate ESN:
1.Turn the vehicles ignition on and press the power button 2. Press and hold Radio station preset 1 and the FM-AM button for more than one second 3. Insert the CD of your choice. A [SEC] message will now aooear on the screen and ESN is active. Anytime the unit loses power you will have to reinsert the key cd.


To deactivate the ESN feature:
1. Turn the vehicles ignition on and press the power button or the FM-AM button (make sure the tuner is on). 2. Press and hold the radio station preset button 1 and the FM-AM for more than one second. 3.Once the display flashes [disc] insert the key cd you selected to activate the ESN. The display should now read [CnCl]. The ESN is now deactivated.


To resume normal operation after the power has been disconnected to the unit:
1. Wait for the dispaly to read [disc]. 2. Insert you key cd, if the correct CD is inserted your display will read [---] and the cd will begin to play. If the wrong CD is inserted it will display [Err]. If you insert the wrong CD 5 times it will say [call 800] and then you have to send the unit to eclipse to have it rest. Good Luck!


How to read the Electronic Serial Number:
1. Turn the vehicles power on. Prss the FM-AM button. 2. Press radio preset button 4 and the FM-AM button for more than a second and the display should show your 8 digit serial number. This number is to identify your unit if it is recovered after being stolen. Yep, that will happen!

Keep in mind that the "security code" in a radio basically fulfills this function, ensure that in case of theft, the computer does not work in another vehicle; I didnt know there was a website to get the radio codes. Before you pay anyone to get your radio security code, I recommend you get on the internet, Eclipse dealers, ask for the parts counter, tell them you need your radio code, have your serial number handy as well as all other numbers off the radio housing.

Or, call 1-800-233-2216 (Fujitsu ten) and they will assist you in the removal of the security code for a $25 charge. the number being displayed is probably the serial number of your unit. If you can remove your radio the SN will be on a tag.

Hope this helps.

The stereo's ESN Feature has activated. High-end Eclipse stereo's have a feature to prevent theft where if the battery is disconnected from the stereo, it must be "unlocked" with a "key" CD, that comes with the CD player but can later be changed to a personal CD of the owner. You would need to either call Eclipse and see if they can de-activate it (you'll need to ship it to them, if they even do it, because it is a security feature after all.) Or you need to talk to the last owner of the vehicle and have them unlock it.

Hi basic101

There is a security cd that comes with the unit originally. You use that to reset the code. without it, is difficult to fix here in this forum. .
There is also antoher way, if you had the unit installed,try playing the first Cd you ever played on the system. That apparant;y is a method for unlocking them also.

Other than that, you may need to get the serial number off the unit and get in touch with your local Eclipse Authorised repair guy.

I am more than happy to answer any other questions you may have about it, just give me a hoy :) If you are still unsure, or have problems, then before you give a rating for this advice, please get back to me and we can try some more things.
Thanks for using FixYa, If you consider the advice I have given you as sound, a FixYa rating is a great reward for my efforts to help you. Cheers.

the unit is locked up eclipse has a feature called esn or eclipse security network. you use a cd to program a passkey that only the owner knows. then if it is stolen the unit is useless. unless you know the right cd cool huh? if the unit is registered to you they will help you unlock it but if not they wont. cool huh. kinda makes you feel good that even if someone does steal your radio they cant use it.. ever.. eclipse also offers a one year theft guarantee out of the box if you register it with them. cool huh..

I need help with one also! I accidentlly locked mine too.
Did anyone tell you how to unlock it? Will you share the trick?
Thanks,

for avn 5435 on the left:press menu and cont ant the same time, while holding them down press menu on the right 5 times

a menu will appear and ask you for a code. you have to call 800-233-2216 and pay $25 for the code. you will have to explain where you bought your eclipse and or know the name of the original owner. if it doesnt match they will not give it to you

with most eclipses they have a security cd feature... what i mean is that the first cd you put in is like a key... remember what cd you used the very first time... put that in and see if it unlocks it.. sounds weired but it worked on my personal player that locked on me i searched all over and the only other solution i came up with was to send it into eclipse for a reset and screw that lol.. ampman
