Okay. In this video, I'm going to show you how to change the key battery in a Honda Pilot. It's a smart key, and this was used from 2016 till present. So this is really easy battery change. If you look at the back here, it's a little knob you can press to release the internal valet key.

And you can go ahead and just take that valet key and right in the middle. If you put it right in between these two pieces of Fob, we're just going to use that to get some leverage kind of twisted a little bit towards you, twist it away from you, and you can just pop this thing right off. And this Fob is really nicely designed and that you're not going to break anything when you pop it off. It's got some good points just to get that leverage with the valet key and pop it off. Now, the internal battery that you need for the pilot is the CR 2032 3 volt coin battery.

And to get that out, you can just on the left side here, take your valet key, pop that out. When you've got a new CR 2032 battery, you'll notice there's some kind of longer prongs on this right side here. If you place the battery in underneath those first, then you can just push it down in. And it makes your life a lot easier than trying to push down through. So make sure to insert the battery that way.

And then take your handy-dandy other side of the Fob, snap that back together. And just one last thing. Put the key back in, of course. And that's it. That's how you change the key battery on Honda Pilot smart key Fob from 2016 to present.

In this video, I'm going to show you how to change the key Fob battery for a Honda Pilot. And this one with the circular, rounded keys here is used from 2005 to 2015. And this is for the Honda Pilot key that looks like this. The first thing I want to do is flip this over and you'll see at the base there's a small Phillips screw. If you have a precision screw set, a screwdriver set like this you can get from Amazon for just a few Bucks.

I'll link to that below the video here. You'll need to start and get that little tiny baby screw out first. And it can be difficult the first time you do it. This one's already been loose a little bit, so it's going to go pretty quick. Once we've got that screw out, there's a notch in the lower left here.

And if we put in our Phillips screwdriver right into that notch and twist, it will create some leverage to be able to separate the base here. And once you have that separated, you can actually pull it towards you and pull that open. Now, the internals of the key here, you can just pull out like so, and then we can set aside the outer case for the time being. Okay, so the key Fob internals. If we look at it like this again, there's going to be another notch in this orientation in the upper right.

So take your small Phillips screwdriver again and just get it in a notch and twist. And that should allow you to pop open these two pieces, give us access to the internal battery here. This little battery is a CR 1616, which we can pop off like so just getting underneath here that will pop out. And we have a CR 1616 3 volt coin battery. And we put a new one back in.

Just make sure the positive side with all the lettering is facing away from you and just pop that back in there's. Not really any overhangs or anything. You can really just push that right back in, put the two pieces back together, and then if you have a light on yours, you can kind of verify that it's working.

So there it is. Okay, so it looks good. Go ahead and reassemble the outer case, pop that back in there, make sure coming through looks good. And then when you're reassembling this outer shell, there's a lip here at the top. If you kind of get that set first, it makes getting the base much easier first, and then you can pop in the base, put in a little baby screw, and that's it

That's how you change the key battery in a Honda Pilot from 2005 to 2015.

Honda Pilot

The Japanese auto manufacturer introduced Honda Pilot in 2003. During the launch, the manufacturer labeled the mid-size crossover SUV as the family vehicle. This was primarily due to its three rows of seats that allow for eight passengers. The Pilot offers significant towing capacity with an all-wheel-drive model having a towing capacity of 5,000 pounds that appeals to many families.

First Generation (2003 – 2008)

The Pilot’s first generation was available as a 3.5 L V6 engine with a power output of 240 hp for the 2003/04 models. In 2005, the manufacturer offered the Pilot an engine upgrade that increased its horsepower to 255, and they featured variable torque management. The first generations of the vehicle were fitted with a four-wheel-drive system that locks rear differential to prevent slippage when driving at low-speed. In 2006, the manufacturer introduced a front-wheel-drive version that had a reduced power output of 244 hp. The new engine also featured the manufacturer’s variable cylinder management system that made it possible to function as a four or three-cylinder engine for improved fuel economy. The first generation vehicles featured a standard five-speed auto transmission.

Second Generation (2009 – 2015)

The second-generation Honda Pilot featured a gearshift at the center console compared to the first generation that had it at the steering wheel for convenience. It retained the Honda variable cylinder management system introduced in 2006 and offered an improved fuel economy. The four-wheel-drive version achieved an average fuel economy of 22 mpg compared to the front-wheel drive’s 23 mph. The second-generation models were available in four trim levels, LX, EX, EX-L, and Touring trims. The powered rear tailgate became standard for the second generation for convenience while the driver’s seat featured two-memory functionality. Optional features for the second-generation Pilot included satellite navigation and tri-zone climate control, power moonroof. Safety features included hands-free calling, backup camera system, traction control, side-impact airbags, and vehicle stability assist.

Third Generation (2016 – Present)

The third generation was introduced in 2016, featured improved body design, and re-introduced the square shape. Exterior features for the third generation included 20-inch tires (some trim levels), daytime running lights, and LED headlights. The third generation is overall more significant than the previous models, although it is 300 pounds lighter. The base engine is a 3.5 L V6 engine that can achieve a 280 horsepower. The model also offers a new fuel economy with an estimated two miles per gallon for in city and highway driving. The models are either available with six-speed auto transmission for lower trims and nine-speed auto transmission for higher trim levels. Buyers of the Pilot have the option of purchasing an all-wheel-drive or front-wheel-drive. Safety features as standard or optional for the third generation include blind-spot monitoring, passenger-side mirror cameras, rear-cross traffic monitoring, lane departure warning system, and multi-angle backup camera. The 2019 model featured significant facelift with new infotainment and design.
