2007 Impala door lock caps?

On my 2007 Impala the plastic caps on the door locks have basically decomposed in the sun - and are now crumbling to bits.
Two questions; any way to get replacements? (Discontinued parts....), and how to get them off?

Not sure how to remove the cap from the rod. In the old days, they unscrewed, and aftermarket replacements were readily available at parts stores (That might still be true. Most parts stores today have one aisle with door knobs and window cranks, etc. So you might find suitable replacements there.)

You can get the cap, with attached rod, online from parts dealers as well as ebay.

This drawing shows the parts for the front doors:
https://www.gmpartsdirect.com/auto-p...ront-door-scat

The rod is item 8 in the pic. The two (left and right) rod part numbers are:

15920295 left, EBONY, TITANIUM
15920296 right, EBONY, TITANIUM

Note there are other part numbers for different colors.

There's no more info - no part number shown - for item 9, but that may be the cap by itself. The rods are on the order of 10 bucks each, so they're not too expensive. That is, you can easily burn 40 bucks of effort pretty quickly trying to find them cheaper

The rear door info is here:
https://www.gmpartsdirect.com/auto-p...rear-door-scat

For the cap and rod, the part numbers are the same as for the front door.

Another consideration is going to a salvage yard.

HTH.

If your socket set is all the same brand, you might be a city slicker.

I'm pretty sure they screw on and off of the rod by just rotating them.

I 3rd the Junkyard option too since they're so small they might not even charge ya for em.

The rod is threaded, but they come up from a rectangular opening, so cannot twist - unless you remove the entire rod, which means removing door panel - something I am somewhat reluctant to do...

Yea - I got 4 new lock caps at the local junk/salvage yard. Just repainted them to a better color - now trying to figure out easiest way to install.

Lock rod position

On a side note, I have wondered about the evolution of the lock knobs, in particular, where they were located on the doors.

In the old days - back in my youth - the lock knobs were at the rear of the front doors, and at that the forward end of the rear doors. One could easily reach thru the front door opening to unlock the rear doors. When the lock knob function was moved to the door handle, the rear ones were still easy to reach from the front.

When the gen8 Impalas came out, I liked it that GM had gone back to the old style lock knobs. I liked the throwback style...except for one thing. For whatever reason, they moved the rear lock knobs to the back end of the door.

It seems trivial...until you have to unlock the rear door while dealing with a dead battery (or some other electrical issue) - then you become keenly aware of why the rear door lock knobs were originally positioned at the forward ends of the rear doors

For sure, there ain't many folks who can reach in thru the front door and unlock the rear on the gen8 Impalas

The door lock “knobs” are fitted to the actuator rod by installing the knob at an angle and snapping it tight. The door panel must be removed, or partially removed to replace the rectangular knobs. You can partially remove the door panel (not undoing the wiring behind the panel), to reach the knob which fits through a bezel in the panel. If you do this, have a helper hold the door panel (with wiring attached), and you can replace the knob. Do NOT pull the door panel too far off of the panel, as you can bend the actuator rods. The panel is designed to lift up and off of the metal door panel lip, while the knob and rod slips through the opening.

There are numerous YouTube videos on how to remove the 8th generation door panels. They are very easy to remove and reinstall. I have removed several to replace defective door lock actuators on 8th generation Impalas, which have the rods attached (on the GM OEM actuators). The rectangular knob at the top is sold separately (by color) and can be easily replaced, or transferred to the new actuator rod.

" The rectangular knob at the top is sold separately" - Where??
Anyway, I got some old ones from a scrapyard, painted them, and am ready to install. As you note, the door panels are not too bad to remove.


However I found that the knobs on the 2006/7 that I found are threaded onto the actuator rod arm.

In general I find that they didn't deal well with electrical actuators and dead battery. I have battery cables in the trunk, but with a dead battery, you cannot open the trunk!!
I wish I had the pull-down back seats, that would solve this.
