security -- staring problem

Asked by Nov 14, 2015 at 10:45 AM about the 2005 Buick Century

Question type: Maintenance & Repair

On Buick 2005 Century, 85K miles, red security light comes on at times
and occasionally it will not turnover or start.  When this happens lights and
wipers work.  No known battery or charging system problems.
Sometimes it starts after wiping key or waiting half hour or so.  Twice I
have had to call road service, then it does start when tow truck comes.  
There is no reason or pattern to when it will or will not start.
Our mechanic will replace the ignition switch for several hundred but
admits that it might not solve the problem.  The local Buick dealership says
they can "probably" fix it for about a thousand.  Discussion boards say you
can completely remove the security system but then other problems may
crop up.
This car is used to transport elderly handicapped people.  With winter
coming I need a high level of reliability.  Any ideas?
Thanks -- Herb

Sounds like the anti-theft module in the steering column is no longer recognising the transponder key. Your Buick is probably involved in the latest GM ignition switch recall. So don't pay for the replacement of the ignition switch!! HTH. -Jim
