What Battery Does a Nissan Qashqai J11 Key Fob Use?
What battery does a Nissan Qashqai J11 key fob use? The Nissan Qashqai J11 key fob typically uses a CR2025 3V lithium coin battery. This battery powers remote functions like locking, unlocking, and activating the panic alarm. Replacing it involves opening the key fob, swapping the old battery, and ensuring proper reassembly to maintain water resistance.
How Do You Identify the Correct Battery for a Nissan Qashqai J11 Key Fob?
The CR2025 lithium battery is standard for the Qashqai J11 key fob. Check the existing battery or consult the vehicle manual for confirmation. Third-party brands like Panasonic or Duracell are compatible, but Nissan recommends using OEM batteries for optimal performance. Avoid using thicker batteries (e.g., CR2032), as they may damage the key fob.
What Tools Are Needed to Replace a Qashqai J11 Key Fob Battery?
Replacement requires a small flathead screwdriver or a coin to twist open the key fob. A pair of tweezers helps handle the battery, and a microfiber cloth prevents scratches. No specialized tools are needed. Ensure the workspace is clean and well-lit to avoid losing small components during the process.
For added safety, consider using plastic pry tools instead of metal to prevent scratches on the key fob’s housing. Precision screwdrivers with a 2mm tip are ideal for prying open tight seams. If using a coin, opt for one with a thin edge, like a dime or penny, to minimize pressure on the casing. Some battery replacement kits include anti-static tweezers and non-conductive tools, which are particularly useful for avoiding accidental damage to the internal circuitry. Always work on a flat surface and store removed screws or components in a magnetic tray or small container to prevent misplacement.
How Do You Safely Open the Nissan Qashqai J11 Key Fob?
Locate the seam between the key fob’s front and back halves. Insert the screwdriver into the notch and twist gently to separate the halves. Avoid prying forcefully to prevent cracking the plastic. Some models require sliding the physical key out first. Work slowly to maintain the integrity of the internal circuitry and rubber seals.
What Steps Ensure Proper Battery Installation?
- Remove the old battery using tweezers.
- Clean the battery contacts with a dry cloth.
- Place the new CR2025 battery with the positive side facing up.
- Snap the key fob halves back together, ensuring no gaps.
- Test all remote functions to confirm success.
Why Might the Key Fob Malfunction After Battery Replacement?
Common issues include incorrect battery orientation, damaged contacts, or misaligned rubber seals. Reprogramming the key fob via the vehicle’s manual procedure may resolve unresponsive buttons. If problems persist, check for water damage or consult a Nissan dealership for diagnostics.
How Much Does a Replacement Qashqai J11 Key Fob Battery Cost?
A CR2025 battery costs between $2-$5 online or at electronics stores. Dealerships may charge up to $15 for OEM batteries. Third-party options are affordable but ensure they meet voltage (3V) and size (20mm diameter) specifications. Bulk purchases reduce long-term costs.
| Retailer | Battery Type | Price Range |
|---|---|---|
| Amazon | CR2025 (2-pack) | $3.50 – $6 |
| Nissan Dealership | OEM Battery | $10 – $15 |
| Walmart | Energizer CR2025 | $4.25 |
Prices vary based on packaging and brand reputation. For example, a 5-pack of Panasonic CR2025 batteries averages $8 online, reducing the per-unit cost to $1.60. Dealership premiums often include labor charges for installation, though DIY replacement eliminates this fee.
Where Can You Recycle an Old Key Fob Battery?
Lithium batteries must be recycled at designated facilities. Retailers like Best Buy, Home Depot, or local recycling centers accept them. Never dispose of batteries in household trash due to environmental hazards. Check Call2Recycle for nearby drop-off locations.
Are Qashqai J11 Key Fob Batteries Compatible with Other Nissan Models?
Yes. The CR2025 battery is used in key fobs for the Nissan X-Trail, Rogue, and Murano. Confirm compatibility by cross-referencing model years and regional specifications. Some older Nissan models use CR1616 or CR1620 batteries instead.
For example, the 2020 Nissan Rogue’s Intelligent Key system also relies on the CR2025, making it interchangeable with the Qashqai J11. However, the 2015 Nissan Altima uses a CR2032, which is thicker and unsuitable. Always verify battery specifications in your owner’s manual or via the manufacturer’s website. Cross-compatibility extends to certain Infiniti models, though using non-Nissan batteries may void warranties if dealerships identify them during service appointments.
“A poorly installed key fob battery can compromise the entire remote system. Always use anti-static tools and avoid touching the circuit board directly. At Redway, we’ve seen cases where aftermarket batteries caused voltage drops, leading to intermittent signal issues. Stick to reputable brands and replace batteries every 2-3 years proactively.” — Redway Automotive Electronics Team
FAQ
- Can a dead key fob battery drain the car battery?
- No. The key fob battery operates independently. However, a malfunctioning key fob left in the vehicle may trigger unintended signals, indirectly affecting the car’s electrical system.
- How long does a Qashqai J11 key fob battery last?
- Typically 2-3 years, depending on usage. Frequent use of remote start or panic alarms shortens lifespan.
- Does replacing the key fob battery require reprogramming?
- Usually not. Reprogramming is needed only if the battery was dead for an extended period or if the key fob was disassembled incorrectly.
