Should You Get a Replacement Key Fob Acura?

When you buy your Acura car, it should come with a key fob.

But these two small remote designs aren’t perfect. For example, at some point, they may not open and close your doors like they used to (that is, you have to hold them super close to the sensors).

Don’t make the mistake of immediately shopping for a replacement. Instead, realize that a dead fob battery might be the culprit.

Replace the Fob Battery Yourself

Replacing fob batteries is easy. To start, take out the metal blade. Then, use a screwdriver to open the tab, remove the old battery, and insert the new CR2032 Button Cell battery (+ side up).

Then, close the tab and reinsert the metal blade. Note that the Acura Keyless Remote design requires two batteries, while the Smart Key only needs one battery.

Going to a Dealer

Fortunately, shopping for a replacement Acura key fob doesn’t have to be stressful. You can always search for a vehicles dealer that carries Acura remote keys. They’ll sell you your key fobs and take care of the programming within hours.

The DIY Route

If you prefer, you can shop for a vehicle fob online. Check out a reputable vendor’s site to find reliable Acura replacement keys.

How Much Is an Acura Key Fob?

When thinking about a replacement, one of the first questions that comes to mind is, “What’s the price?”

Your automotive dealer knows you have luxury vehicles and will jack up the price of a replacement Acura key fob. If you contact your dealer and buy through them today, expect to set yourself back at least a couple hundred dollars.

With resellers, however, an Acura keyless entry replacement is much more affordable. Reputable sites make it easy to search for a price less than $100 on key fobs for 2021’s best vehicles. Plus, they provide excellent customer service along the way.

How Much Is Acura MDX Key Fob?

The price will depend on several factors, like the seller, how old the key fob is, etc. However, you’re going to find the lowest price by shopping online rather than using a dealer’s service today. This price information is especially relevant if your Acura car is a model from an older year.

How Do I Replace My Acura Key Fob?

When you get your Acura key fob replacement, it’s not going to work out of the box.
