Key and column issue

[Earthway69]

Just recently sometimes when I start my c5 I get a message to remove key for 10 seconds then restart. What is the deal with that? Never saw that before. Any help would be appreciated. Thanks

This sounds like the start of the "Column lock" issue. Maybe your car has had the GM 'fixes' done to it, but many go beyond that. But, my first suggestion is to check the battery. Many issues have to do with a battery which is not up to snuff. I posted a link (which I will find and post here in a few) by one of the top Corvette mechanics in the US (C4C5specialist). His seminar at CAC Cruisefest a few years back was aimed just at this particular issue.

I'll find the link and post it in this thread soon.

GM recalls never worked unless they actually modified the column itself. Batteries can cause the issue but there are plenty of cases where it did not.

I consider the LMC5 to be the best Column Lock problempermanent fix out there. It also does not require you to “undo” any previous CLattempts to resolve this issue. Their eBay ads have a good video that shows theinstall at the BCM. It does not cover everything in the written instructions.So, read the instructions and also here is some extra info. In some cases, theBCM timing is off just enough to cause some issues. They make several versionsand they can swap out/provide one of these if you have any issues. Theircustomer support is as good as it gets.
Not uncommon for people to "put the column in a pre-lockcondition" and not know it and then start with the install. In otherwords, they started with the column lock “energized’ even if it was not actuallylocked yet. If not actually locked yet, it will be as soon as you turn thesteering wheel after the LMC5 install. It will then remain in the lockedcondition until you cause the motor to unlock. It will then remain in theunlocked condition since the motor is then unpowered with the circuitsdisconnected.
Here is one way to prevent that if your column locks andunlocks normally:
If the CL isfunctioning normally you don't not need the Unlocker, merely turn the ignitionON, pull fuse #23 in the I/P fuse box, turn ignition OFF, turn the steeringwheel (left and right) and verify it is unlocked. Next, disconnect the negative battery terminal,re-insert fuse #23 and continue with the install.
Also the 1999 and later C5's have a column lock relay thatcan be unplugged or else it will be powered and could fail and drain thebattery. The LMC5 written guidance provides this info. This relay is above theBCM.
They also have a great install video in their eBay ads youneed to watch.
