Folks,

My wife's key sounds a little grindy when being inserted in the ignition (or the door). My key isn't so "grindy".

I don't know if that's an indicator of a bigger problem.

My instinct is to just add a bit of key lubricant - or maybe even WD-40, but I don't know if that would screw up the anti-theft characteristics of the key or lock or something else.

Would appreciate your help.

 

WHAT YEAR IS IT?

I wouldn't hesitate to spritz a small amount of Water Displacement, 40th formula (WD-40 : ) into the keyway.

You might also consider something with silicone in it, instead of WD-40, but I would use WD-40!

Don't want to use WD40 in locks you are better off to use powdered graphite.

 

Exactly what I was going to say. For locks: WD40=bad. Graphite=good

 

Yes, you can use graphite in old style pin tumber, or wafer type cyliders, if you choose to.
(I will continue to use WD-40, as I have for the past 20 years in this business.)

Graphite is abrasive to new style car locks.

Especially laser-key type wafers!

Graphite is a form of carbon, as is a diamond.

Thousands of locksmiths ought not to be incorrect in this assessment.

¿WHY do you say that?

 

The car is an '09 Fit Auto Sport - so it uses the key with the "electronic circuit". So I'm concerned that the wrong lubricant would screw up whatever circuits might be embedded within the key.

 

Mmmmm... Play it safe and take it to the dealership?

 

You will not be spraying it on the key.

Besides, the transponder is embedded into the molded plastic head of the key.

I've read that it will survive a wash cycle in your washing machine!

The transponder circuitry, located on the exterior of your ignition cylinder, is isolated from the keyway.

HTH!

I agree!
