It is very important to know how your smart key functions, especially in times of distress. Your salesperson should have taught you about it when you purchased your new Prius. People come in into the dealership all the time asking for aid and are amazed to discover that there is a battery and/or a manual key tucked inside the fob.
It’s pretty easy. The key ring is connected to the hidden manual key. To eliminate it, just slide the tab on the end of the fob and hold it while pulling on the key. It should slide out easily, even though it might be a little stiff the first few times.
This design Permits You to get you into your car should the battery die. This will allow you to go purchase a new battery replacement right away.
To start the ignition, just hold the fob up against the ignition button and push the start button. There should be only enough juice left in the battery to get your vehicle started.

Just replace the batteries when the warning light suggests that it is time and you shouldn’t have to worry about being obstructed out. A Wise driver may even keep extra batteries on hand in case of an emergency.
Changing the Battery
Most smart keys, regardless of the model and make of the automobile, have a small battery that is easily replaced. These batteries are generally referred to as “watch batteries.” Don’t allow the dealership cause you to believe some fancy battery is needed or you can not replace it yourself. Changing the battery is actually pretty simple to do if you understand how to open the fob.
Here in the Toyota dealership, we Charge $12.50 to install the battery for you. You can easily find exactly the same batteries at locations like Walgreens, Walmart, Best Buy, some other major retailers. In the chain stores, the battery will only costs you about $3 to $4 per cent, and obtaining a multipack will help save you even more cash. Store the extras in your glove compartment and you won’t be stranded again. Amazon.com is normally the cheapest, sometimes for as low as 39 cents, so economical that even dealerships order them to sell at a mark-up to customers.
Since they are always on and trying to find a sign, their batteries have a tendency to die at around precisely the exact same time. So when you replace one, you might as well receive a multi-pack and replace both your key’s batteries together.
How to Replace the Battery
Not Understanding How to start the smart Key is the number one reason that people choose to pay to have the batteries changed for them.
Eliminate the spare manual key that’s tucked within your key fob. Locating the sliding tab on the end of the fob. It’s on the end that the Keyring is connected to. By sliding the tab off from the ring and holding It, you can pull the spare out of the base.
Once the key is out, you want to slide the same tab over and hold it, while slipping off the rear of the casing.
Once the trunk is off, remove the four tiny screws which pay the battery plate. I highly recommend using a magnetic screwdriver to perform this. This helps Prevent dropping and dropping the screws and also makes it a lot simpler to Place the screws back into the base when you are done.
Once the plate is off, the battery could be popped out with another small screwdriver or anything else small enough to dislodge it. Be careful not to harm any of the internal components, as these are rather expensive to replace.
WARNING: These Could Drain Your Smart Key Batteries
Do not store your smart key near (closer than 1 meter away from) some of the following devices:
TVs or Computer Screens
DVD or VCR Units
Desktops PCs or Laptops
Cordless or Cell Phones

Which Battery Do I Need?
CR2032 is the battery dimensions of Most Prius Smart keys, but be sure to look at your fob before ordering. It could take a CR2016 or another size depending on the vehicle’s production date. Catch a multi-pack and store them in your glove compartment to stay ahead of the game.
In the dealership, we use Magnetic precision screwdrivers, which I highly recommend as the internal Screws are tiny and easily lost.
Internal vs. External Key Cuts
What’s the Difference?
There are two forms of important cuts. Some automotive brands utilize both types of cuts and others utilize either the internal or the external cut.
External. Most traditional Keys have outside cuts. Think of your home key. Into the outer borders of the shank.
Internal. But lately, more and more automobile companies have been switching to internal reductions. The main distinction is that the cuts are made on the interior, with the outer borders of the shank left smooth. Lexus continues to be using these internal cut keys for awhile and now Toyota is beginning to use them on most of the newer versions. The principal advantage is security, but they’re more expensive.
If your vehicle requires an Internal cut, you are taking a look at adding approximately $100 to the cost of replacing lost keys. The reason is that they require a costly high-tech laser cutting instrument. Most traders choose not to create the investment to get their own laser cutting machine. Therefore, they have to purchase from the producer, which increases the time required to complete your purchase and also increases the price.
Unfortunately, you do not have a choice on which that’s determined by the auto manufacturer’s make and model.
Protect Your Smart Keys with a Finder Kit
For cars like Toyota Prius, it is Very expensive to replace keys. Protect your investment with a wonderful pair of finders, electronic key rings that have a built-in finder and beeper.
I see people daily that have to invest $300+ for a single lost key and several of them ask about a product like this. It won’t help you after your keys are already lost, so don’t wait.
Tips for Saving Cash & Frustration
Wise keys are rather expensive to substitute. Most clients are completely shocked if they find out that you the hardware is expensive itself, also it will have to be programmed in a dealership. Not only does the Keyless entry have to programmed and place to coincide with your car or truck, but a lot of keys Nowadays have an immobilizer chipset that also have to be programmed to fit The onboard computer, which may only be achieved at the dealership. Paying for the hardware in addition to about one hour’s worth of labor for your programming.
What to Do to Find a New Smart key
It must be present for your own programming.
Bring a working key; without one, there will be an additional 30 – 60 minutes of labor added on your bill. The master technician must contact the manufacturer for permission and to find a special override code. This can take one hour or longer on top of the hour of programming. With some versions, you could be forced to replace the automobile’s onboard computer, and this can be exceedingly costly.
Make an appointment. You can’t simply walk into a dealership to have a key programmed. Having an appointment ahead of time is called for at most dealerships.
Some clients try to save cash by purchasing online via eBay, Craigslist, or an online parts depot. This is not consistently the best idea, however
Be Careful Purchasing Replacements Online
While it might seem to be a fantastic idea to save yourself some extra cash by bringing your own replacement fob to get programmed, often it ends up being a wasted cost.
Why? The majority of customers Who bring in their own that they bought online were offered the wrong product. It is a high tech part of gear: You can’t just buy one online and expect it to operate. Even when you provide the correct year, make, and model, chances are the one which you receive will not be programmable for your vehicle.
If you do intend on purchasing a Replacement online, here is one way to help ascertain if it will work: Before you shed your fob, make sure you create a note of its own information. There’ll be a decal on either its interior or outside. It could be visible after removing the sliding back, the sticker may be on the exterior, or the information might be etched into the plastic material itself. Allow me to repeat: Take notice of this information now, before you lose your keys and can’t access it.
What you’re looking for is the Following three numbers:
MDL #: Model Number, FCC: Federal Communication Commission Number, and IC: Manufacturer’s Universal Code.
In order for it to operate, you have to buy one with these specific same amounts. If these amounts do not match, your replacement won’t be programmable to your vehicle. This is very important. If you’re trying to buy a used fob out of somebody, simply have them find the information and examine it to you. If all numbers match, then the fob should do the job. If the amounts don’t match, then don’t waste your time or money!
When comparing prices to the Dealer’s costs, always remember to work in the price of shipping. I am amazed At how many clients neglect to compute the delivery charge in their final price comparison.
