Default Key ohm Values

My three original ignition keys on my '89 measure 745, 746, and 747 ohms. None of these appear to fit within the ranges listed on the various websites such as vatsucks, etc.

The closest is key number 3 which is a range of 650 to 728. Will this work when ordering a bypass kit?

Are you sure you are not missing a 0 at the end?

I believe you likely don't understand your meter. Drive by a dealer and have them 'drop' the key in their VATS Interrogator for a resistance check. I believe I understand what you likely have but I won't just toss it out there.

Why does 'by-pass' even interest you?

Thanks for the response, fellers. The list I am using on vatssucks has the resistance numbers starting at three digits -- hence my reporting the three readings in three digits. If you guys are saying it should be four digits (with a zero on the end) then I see on the list that this would be key code 13 or a target 7500 value. The kit is only 30 bucks, so I will give this a shot.

By-pass interests me because I don't want to sit in a parking lot 30 miles from home on a 90 degree day waiting on the thing to reset. The car already has the "manual shifter" theft protection so I don't see the need for another layer along with the cut key.

The readings you are getting would make sense if your meter is set for X10 on resistance.
