Highlander Key Fob CR2032: FAQ
Does every Toyota Highlander key fob use a CR2032?
No. Toyota manuals list CR2032 for Highlander smart keys and CR2016 for standard-key remotes. The 2026 Highlander manual lists CR2450. Always match the size in your own manual or on the old battery.
What comes in the Deluxe Lithium CR2032 3V pack?
Two CR2032 3V batteries. A routine key fob change uses one. The second is a spare. No key fob is included.
How long does a Highlander key fob battery last?
Toyota gives a standard electronic key battery life of 1 to 2 years. The battery drains even when the key is not used. This is Toyota’s general figure, not a guarantee for any one brand.
Is the Deluxe CR2032 rechargeable?
No. The pack is listed as single-use. Never try to recharge it.
Do I need to reprogram my Highlander key after a battery change?
No. A routine battery change in the documented smart-key design does not need reprogramming.
Can I use a CR2016, CR2025 or CR2450 instead?
No. Toyota says to use the battery type named in the manual or a type the manufacturer recommends. Similar names do not mean the cells are interchangeable.
What if my key fob still does not work after a battery change?
Confirm the battery size, check the positive side is up, make sure the cell sits flat against the contacts and the case is fully closed, then try a fresh CR2032. If it still fails, the fob may have a fault.
How should I dispose of a used CR2032?
Do not put it in household trash or recycling bins. Tape the terminals or bag each cell individually and take it to a battery collection or household hazardous-waste service. Keep used cells away from children.
