Westy, August 2017

Hi All, had problem with broken wires leading from keypad ( 97' 406 TD ). Repaired wires before and approx. 1 year later same issue. Repaired wires again in order to start engine, then with engine running, disconnected connector block from keypad. Engine now starts independently. NO MORE KEYPAD. Many thanks to all on this site or the info. Any questions then please feel free to call me on 07753 475570. Simon.

hi i got a 97 406 and all wires on keypad broken off how can i start the car or bypass to work

gerrie, May 2011

I had the Red and Green light on my Immobiliser on my Phase 1 1996 D Turbo.
I rang up Peugeot and they said it will cost alot to fix so it isn't worth doing. Me being me (Stubborn), I got the old 306 on a ramp, and had a look at the wiring loom at the N/S/F next to the radiator under a flap.
Luckily I found two wires were split/slightly corroded. I connected the two wires together, cranked the car and she started!
As soon as i'd done that I quickly disconnected the immobiliser and I don' have to use it again.
I hope this helps someone with their 306.

Had the problem on my 1996 petrol 406, red and green lights on simultaneously. Checked the back of the keypad and found 4 broken wires. Rather fiddly to replace the wires as they had broken off at the entry to the multiway connector. After fixing the wiring I removed the connector with the engine running (as suggested elsewhere) and now the immobiliser is bypassed. So a huge thank you to this website.

Simon, March 2011

i got a 406 hdi 51 plate immobiliser is on cant get it off with key and iv not got the code what can i do so i can drive again lol thanks

kman, February 2011

I had this problem on my car, there is a box on the n/s/f of car at the bottom next to the radiator, with all the snow my wires got wet and erroded, i reconnected the wires, it started fine and i disconnected the immobiliser after reading all the horror stories on the net.

Marcus, January 2011

shaun, November 2010

If the vehicle is still running you can uplug the multiplug connector and the keypad will no longer be required

alex y, October 2009

Before you bypass check the wires that go into the plug at the back of the keypad. Today I checked mine and after stripping the protective sleeve back there were THREE broken wires. They are so thin they break easily. I just stripped the colour coded wires back and twisted them together and soldered them and wrapped them back up in electrical tape. All working fine now.

Johnny, July 2009

My immobiliser has messed up also. N reg 406 TD. After I removed the stereo. Does the stereo wiring have anything to do with the immobilser?

johnny, July 2009

My wife got stranded when the 406 keypad failed to work. AA man undid panel directly above keypad and advised giving the wires 'a wiggle', and that it will work to keep doing that for a while. hmmm

toby, May 2009

hi today i have bypast my imoberliser on 19 TD 806 1998 you simply take one live wire to the ecu which wire i here you say here goes then there are two red wires one has a blue band round it its not that one so put live feed to the other one then start car simple as that (let me know if it worked for you )

Help!! I have a key transponder immobiliser but cant start the car. How do I get the immobiliser off?

dave, November 2008

Peugeot immobiliser keypads showing both red and green lights can be reset by turning ignition on, and leaving on for about 30 minutes.

JJ, July 2008

We have immobiliser problem red light goes to green when code entered but nothing we or the garage could do would make the car start. I bought the car for my son to go to Glastonbury next week he is 18 and it was only £400 it went great for two days then on the third it wouldn't start he got out locked it unlocked it got in and okay but the next day it wouldn't start and we have tried everything ever since but no joy. if anyone does know how to neutralise the immobiliser if the car won't start please can you email jennie.chapman@falmer.brighotn-hove.sch.ukme as the garage say only peugeot can do it and its £200 which we haven't got.
Jennie

jennie chapman, June 2008

I had this problem with a 306 petrol with the keypad system it runs through the ecu so all i did was got an earlier ecu out of a 306 that didnt have a keypad system just the standard alarm on it and just plugged in the ecu and it started straight away it just means that you have no immobiliser on the car anymore hope this helps it worked on my car

Rikardo, March 2008

I also get the green+red lights on, cant enter any code or start the car....any ideas welcome

Michael, March 2008

Answer to all you guys out there. Peugeot keypad probs. The easy way! Take a live feed from battery + into car dash(or anywhere only you know) add a switch take cable from other terminal through to engine bay and connect to stop solenoid on fuel injector pump. If ure unlucky to have a metal cover over yours and dont want to spend a day removing the pump, the only (brutal) way is to attack it with an angle grinder. remove intercooler if its a turbo. Took me 30 mins so far. Next find the starter motor feed on ignition switch. Scotchlock new cable to feed , run through to engine bay and connect to starter after removing original cable. REMEMBER both these cables are from a live feed (positive) if these wires rub through accidently touch chassis you could be claiming on your insurance!! Be a good idea to put an inline fuse in pump switch. Ignition should be ok . Good luck . Ian

Ian, February 2008

My peugeot 306 diesel estate had a key transponder immobilizer. After the battery went flat the immobilizer kicked in and cut fuel to the diesel pump. After many hours surfing and many recommendations I decided to remove the immobilizer completely.............by striping down the area and using a grinder. Like this....

Lynne Smith, November 2007

i have same problem need to bypass key pad on my n reg 406 petrol any help greatly appriciated email sjpdesigs@hotmail.com

steve, October 2007

same problem, peugeot 306 turbodiesel 97P (keypad immobiliser), after the battery was disconnected to change the starter, the red and green lights come on togther a couple of seconds after turning the key to the 2nd position (without touching the keypad). Then pressing number keys gives beeps but no confirmation beeps after entering 4 numbers. It cranks but does not start. Tried all the usual things (leave it on for >1hour to try to reset in case its locked out, checked the plugs+wires to the diesel pump, press the fuel cutoff / inertia switch).

I need a cheap fix or i'll have to scrap the car. If anyone can help pls email robert_a_buckley at hotmail dot com.

cheers
