Honda Key Fobs — Everything You Need to Know

Honda is a Japanese car manufacturer and has designed some of the most beloved cars in recent history. These models include the classic Honda Accord Type R and the timeless Honda Civic (in all its much-loved iterations).

A modern Honda car typically comes with a keyless entry remote. But what’s the best Honda remote to add to your cart? What do you do when the battery in your Honda remote needs a replacement? This guide covers the major types of key fobs available and how to change batteries in the remotes for these wonderful vehicles.

Honda Rectangular Button Smart Key Fob

This remote control is the newest model available to add to your cart. It’s a great option if you’re looking for keyless entry fobs for your car. It can save time with handy lock/unlock buttons and works with most models.

You can get these remotes from an automotive dealer with your car or purchase them from an online electronics store selling car parts and accessories.

These fobs come with lock/unlock buttons for the car and the option to choose which side to open for quick entry.

Replacing Batteries in a Honda Remote: Step-by-Step Guide

So, let’s cover how to insert your new replacement battery.

  1. Slide the back of the key fob away. You don’t usually need any special tools for these remotes.
  2. Remove the old battery. Check the number on the battery (e.g., CR2032) and make sure it corresponds to the number on the replacement battery.
  3. If you see that any cleaning is required on the battery site, you can do this now. Keeping your remote clean before you close it back up may prevent grime from interfering with the battery.
  4. Click each button and check the results are as you’d expect (i.e., doors/trunk close and open properly, closed doors lock, the vehicle starts normally) after putting the new battery in your remote.

FAQ

How much is a Honda key fob?

The keyless entry unit typically comes with vehicles you purchase from a dealer. Vehicles from third parties may come without a remote, in which case you can search and view automotive keyless entry remotes online.

Even including shipping, these remotes are typically very cheap and work for most Honda vehicles. Contact the seller of any remote you find from an online search and ask them to get back to you about which vehicles the remote works for, including the year of release. This is an easy way to save time and hassle in online sales — if the seller doesn’t message you back, they’re not trustworthy.

What battery does the Honda fob take?

Key fobs from Honda use a variety of batteries, but the good news is that:

  1. If you have an account on a popular online retail service, you can find all of them with a quick search and add them to your cart.
  2. These batteries aren’t free, but they are pretty cheap to add to your cart.

CR batteries used in key fobs and vehicles using electronic car key options are widely available. We recommend that you check the number on the battery displayed before purchase. Then, view it again when the product arrives and before you open the plastic.

Pro tip: CR1616 and CR1620 batteries are similar, but the CR1620 is thicker. If you insert a battery into an electronic entry key and it doesn’t close properly, it needs the thinner CR1616. Likewise, if the battery rattles around when the entry fob is closed, you need a thicker option.

What if my Honda key fob battery dies?

Your dealer may say, “call us if your fob dies,” but you don’t need to contact a professional simply to replace the battery. This is a service you can perform yourself if you follow the instructions further up the page.

How to program a Honda key fob?

If you have a new remote, you may need to call a locksmith to program it. A car dealer may also say, “call us to program your remote,” but if you don’t buy vehicles or remotes from them, they may be less forthcoming. For this reason, it’s good to have a locksmith’s number if you’re close to buying a new remote entry device online.
