Nokia 1661 Security Code

I turned my Nokia 1661 phone off yesterday and now whenever I turn it on it asks for a "security code". I have tried 12345 and 1234 and 00000 but none of these codes works. I have no idea how this happened - did this happen to anyone else? If so how was it fixed.

Sounds like either you inadvertently added a security code to your phone or a prankster did it for you ;)

If this is the security code that locks the phone then there may be some way to reset it e.g. this. You can Google on `reset nokia security code` for more information on other possible solutions.

If this is a SIM PIN then you should call SO CS for the PUK code and related information about resetting the PIN.

Thanks for your help! The code generator didn't work for this model, but I took out the battery over night and then tried 12345 again and it worked.

Same thing just happened to me. The phone has been on the shelf since I last used it. Is it possible the phone can be inadvertently locked remotely?

I guess I am going to try that battery trick tonight.

Woo hoo I just had a second near phone death experience. I'd had the same security code problem and ended up getting another Nokia 1661 and moving my sim card over to that. Fine. Then tonight I extremely impatiently and stupidly tried to add something to my reminder list while the phone was on the charger and IT ASKED FOR A SECURITY CODE!!!! My life flashed before my eyes until I remembered the 12345 code. Since it had just happened, the crops were saved. Hope this may be of use to someone before it's too late. SO customer service told me inadvertently locked phones happen a lot.

Had this same problem "suddenly" appear on my 1661. Not sure what triggered it! No combo of usual PIN's, 1234, 12345, 9999 etc worked at all. Spoke with SO CS who advised me to call Nokia directly.

I just spoke with Nokia (888-226-6542) and for the 1661 what they told me is:
- if you enter even ONE incorrect code, the default 12345 will not be accepted
- to reset to the default code, so the following:
- turn off phone
- remove battery
- press and hold POWER button for at least 10 seconds
- replace battery and cover
- turn phone ON
- do not touch keyboard for at least 15 minutes
- default 12345 code will now work

and what do you know ... it did work. Hope this helps someone else!

I had this same problem, but I called the SO rep.

She told me that it's now a known defect with this phone. She basically asked me to "power cycle" the phone.

Meaning to turn off the phone, take out the battery, wait 15mins. Put in the battery, wait 15mins, then turn on the phone for 15 mins. Then eventually the code 12345 will work. I did that for the entire afternoon and finally got it to unlock.

Today another scary "defect" showed up. The phone was reporting NO SIM CARD. I restarted the phone a few times and finally it was able to detect the sim card, but all my phone settings including time and date were wiped.

I feel that this Nokia 1661 phone is not very reliable. So many problems for a phone with so little features.

I also had this problem last weekend, while recharging my phone. It just locked up! Fortunately, the security code worked (after a while) but all my lists were gone and my preferences had to be reset (the SO Cust. Rep. asked if I had the 1661 as this model seemed to be prone to this problem)
Then, while trying to set my ring tones, I kept getting a prompt for the security code! I was advised to restore the factory defaults.

A similar thing just happened to me. I used the phone yesterday and shut if off for the night, but when I tried turning it back on today the phone (Nokia 1661) would not respond at all -- just a black screen. I had to remove the battery, re-insert the battery, and then the phone would turn on; however, I was then prompted for a security code. 1-2-3-4-5 did the trick, but now all of my settings are gone. I also can no longer select a new ringtone. When I try, the phone turns off, turns back on, and I need to re-enter the security code again. I got the phone free when I purchased a $100 airtime voucher, so I really shouldn't complain -- but c'mon... ... ... If the phone has this kind of widespead malfuction, you'd think Nokia would recall all of them.

I was having this issue happen to me about once per month. I also had a problem where the phone would stop ringing. It was getting really annoying, so I sent it back to Nokia for warranty service. They updated the software and returned it. Since the update I have not had a problem.

If you have this problem, I recommend returning it for a software update.

You have to pay shipping to the service centre, but the return is covered. I just put it in a padded envelope and shipped it by Canada Post for a few bucks. It was well woth it.

For some reason the phone ask me to enter security code every time i turn it on, and all the call history information are erased. Also I have been wondering why I missed so many calls in the past few weeks - perhaps it was because the phone wasn't even ringing. It seems that there are a lot of problems with this phone.

Ran into this problem a couple weeks ago. I fixed it following nancam's instructions (thanks!).

Afterward, my phone wouldn't ring, and whenever I tried to change the ringtone, I ran into the same problem as GoTeeGuy: the phone would power itself off — requiring the 15-minute wait again. Selecting Settings / Restore factory settings fixed the problem. (This wipes everything, returning the phone to its initial state.)

I also changed the security code: Settings / Security settings / Change access codes / Change security code.

just wana extend my thanks to nancam for your post helped. for a while, i thought of pawning this 1661 nokia away.

...i've been using this nokia 1661 for 11 months(start feb2010 and going), so far no problem and then
one day, when i check to see if i have some messages on my phone, the screen asked for a "security code" and what can i say, i entered 1234, did not work, i entered my PIN, also did not work. i entered a lot of number and other combination i know off. all did not work. since you can just plug in some number, i just keep on plugging. no maximum limit of try anyway. then i gave up. this phone is bricked i assume. so i googled some info about this and it seems, this is a common problem for this (sorry) crappy but goody cheap nokia 1661 phone.

my first try actually did not work. what i did is that i removed the battery from the phone for one night. then i put back the battery, and when it asked for security code, i entered, 12345 = does not work. so i review again what possibly did i miss on this forum. and this is what i did miss (from nancams post):

"do what nancam said".... then
....
– press and hold POWER button for at least 10 seconds
– replace battery and cover
– turn phone ON
– do not touch keyboard for at least 15 minutes
– default 12345 code will now work

so it did work. after waiting for about 20 minutes i put on 12345 and now i am IN.
i turned off my phone. turn it again, and it asked again a security code. i put 12345 and i am in.
i then set the security level (from the phone settings) to off so i dont need to plug that 12345 everytime i turn it on. so far so good, im back on using my old phone. so what basically happened on my phone after this "security code" brohaha?

well, all call lists are gone. (dialed numbers, missed calls, received calls, etc) but phonebook and messages data are still there.
