I hope it IS the battery and not anything else. I lost my other key 5 years ago when my dad died since I was so upset I was screwing up a lot of stuff. I asked the Honda place how much a replacement would cost and they told me over $400. I had a stroke! Needless to say, I never replaced it. My fixed income sucks. I think I can get a battery for under $10 after reading and watching the DU replies.

I can put new soles on boots and I make earrings so I have a ton of supplies and I feel confident that I am up to the task. Thank you!!!

where I can get a replacement key with alarm for under $400? It seems like a rip off from the car companies. Is there a secret place that does it cheaply?

just a couple bucks

and it looks like I can get one pretty much anywhere for under $10! I was NOT expecting that. I needed good news this week and this lifted my spirits a bit since I have to pay $350 for a computer place to "clean" my desktop computer which I only use about 4 times a year after it was scammed last Tues. I am pissed off over that and will be until the day I die.

be able to replace it, but you have to have the spare key FOB or it will cost considerably more.

If it is the battery isn’t it a standard battery?

narrow the problem down. I think, I mean I HOPE, it is just the battery and not a whole new key. That is supposed to cost hundreds of dollars for some reason. Why are new one so expensive?!?

32xx battery.

Anyway good luck

battery in a 2010 Honda CRV key. There are videos showing about everything. I have a 2020 CRV I replaced the battery in my key in less than 5 minutes, the battery cost about $2. I bought mine at Kroger, Walmart also has them.

to get a battery replaced (I'd been planning on getting around to it) and I'll ask the watch/ jeweler if he could sell me one cheap or I can just pop next door to Ace Hardware or CVS.

Started out replacing watch batteries for my family, this has now grown into replacing batteries on all sorts of devices. From garage door remotes, to glucometers, laptops, guitar multi-effects pedals, and anything with a button-type battery. I have a great assortment of batteries which I buy from eBay. Prices range from $0.75 to &1.00, if you buy 2 to 10 or so. Sellers usually list the expiry date, if they don't move on.

Posting this in the event the battery doesn't fix the issue. You will need all the keys available if you're having to program a new key fob.

Since a replacement key with an alarm is over $400 and I only have the spare with no alarm/fob and one with a working alarm. I discovered that my car wouldn't start yesterday when I had planned to buy a battery at CVS for the key. I charged my car for about 15 minutes last night and wondered if my suddenly dead car battery had anything to do with the key not working. I tested it out before my car battery was fully charged and the key's alarm works!

I watched this video and I want to do that! I want my spare key/alarm again but looking at the video I wondered how he got the key cut for his specific CRV. I can buy one like this and program it myself and save several hundred dollars but the key he got from Amazon doesn't appear to be cut along the edges like all keys do. Am I missing a step?

I purchased a key fob from a Ford Dealer whose parts department sells parts on eBay. Its best to go with an OEM key over some cheap aftermarket. Some dealers market parts on eBay to augment their usual sales to other dealers and local shops. I found this one on eBay, Galpin Honda is the seller and they are a Honda dealer in Southern California.

I then took my new key fob to a local hardware store to get it cut. This is the riskiest part, as you need to find a place that cuts keys frequently and won't mess up your new key.

Once the key is cut, try it out on one of the CRV's locks not tied to the ignition (read: vehicle's onboard computers). The trunk/hatchback, glovebox, or locking center console are good candidates. Once you're sure the newly cut key works in the locks, proceed with programming. Drive home and do the programming there, in case things go awry so you're not stranded somewhere.

Once your new key is programmed and will start the CRV, drive the vehicle with the new key, but keep the old one with you anytime you drive just in case the new one fails (that can happen even with keys bought directly from the dealer). Once you're confident the new key works (a good threshold is a week's worth of vehicle use), pull the battery from the old key and put it away somewhere you can find it such as with the car's title.

Do not dispose of the old key! The keys that came originally with the car are hard coded into the Body Control Module (one of several computers that run vehicle systems). Losing or throwing away that original key means you would be compelled to take the car to a Honda dealer if you ever need to program additional keys in the future.

Good luck.

and I am grateful. I do not understand car's computers at all and need to have step by step instructions. I am saving this!!! Thanks!

Did you know that if you don't drive often your car won't pass the CA Smog Test. It turns out that to trick the computer I had to drive non-stop between 50-60 mph for about 40 miles, then stop and wait for 1 hours then go back at 50-60 and it will pass. Odd!

I think I replaced the batteries in the FOBs of my Saturn Relay over the years several times. Had to replace FOBs once or twice over the years. They were "reasonably" priced at about $90 from the dealer.

Relay has gone to go "live on a farm" after the wife totaled it last year.

Dodge Caravan and Honda Odyssey needed an additional set of keys. FOBs were about $300+ each from a local locksmith. About the same or more from the dealer.

Odyssey was easy. Buy it, wait to arrive, locksmith programs it in minutes, pay, and out the door.

Caravan was a beast. Buy it, wait to arrive, and locksmith cannot program it despite a significant effort. Running around, YouTube watching, research, visit back to the locksmith twice, visit two different dealers, and for $10 I got the four digit key FOB PIN, which I needed in order for the locksmith to program the FOB. A few minutes later, with the PIN, programmed.

involved it buying a new battery as well as programming a new key yourself. Then an idea came to me. The same time my key alarm stopped working was the same time that I had left a door slightly open and drained the car battery, even after I charged it the day before.

Bingo! I recharged the car battery and tried the key alarm again and IT WORKED!!!

I learned something new and as a 61 years old I am still an old dog learning new tricks. It is exhausting though.

Do they cut specific cars there? I have been there before but mostly for wipers. I never checked the keys out.
