How To Open A Rear Door That Will Not Unlock

[aspire_helen]

I have spent some time fully dismantling two "faulty" rear locks and have devised a guaranteed method of unlocking a rear door from the inside.    Once the door card is removed my method takes less than 10mins and uses only a soldering iron and instrument screwdriver.  The door and lock remain undamaged and useable.  

 

Please see the attached PDFCITROEN C5 - Opening an unopenable rear door PDF.pdf.

 

I can provide my more detailed analysis of the lock if anyone wants it.

Oops! Of course I meant How to Open a Rear Door that will NOT Unlock.

Can someone edit it??
