How Do You Replace the Battery in an Avital Remote Car Starter?
To replace the battery in an Avital remote car starter, locate the battery compartment on the back of the remote, open it with a small screwdriver, remove the old battery, insert a new CR2032 3V lithium battery (ensuring correct polarity), and securely close the compartment. Test the remote to confirm functionality. Always use gloves to avoid oil transfer to the battery contacts.
What Tools Are Needed to Change an Avital Remote Battery?
You only need a small flathead screwdriver or a coin to open the battery compartment and a replacement CR2032 lithium battery. Avoid using metallic tools near internal components to prevent circuit damage.
How Do You Identify a Low Battery in an Avital Remote?
A weakened signal range, unresponsive buttons, or an LED light dimming/flickering indicate a low battery. Some Avital models display a “Low Battery” warning on your vehicle’s dashboard.

Advanced symptoms may include intermittent functionality where the remote works only at close proximity to the vehicle. For remotes with LCD screens, icons may appear faded or incomplete. Temperature fluctuations can exacerbate these issues—cold weather often accelerates voltage drops in aging batteries. To confirm, test the remote’s signal strength by standing 30 feet from your car and pressing the “Lock” button. If the response is delayed or absent, a battery replacement is likely needed. For key fobs with dual functions (e.g., remote start and trunk release), note if only certain features fail, as this could indicate a deeper electrical issue rather than just a low battery.
Why Use a CR2032 Battery for Avital Remotes?
The CR2032 provides 3V of stable power in a compact size, matching Avital’s voltage requirements. Non-lithium alternatives may leak or underperform in temperature extremes.

| Battery Type | Voltage | Lifespan | Temperature Tolerance |
|---|---|---|---|
| CR2032 (Lithium) | 3V | 12–18 months | -30°C to 70°C |
| LR44 (Alkaline) | 1.5V | 6–8 months | -10°C to 50°C |
Lithium batteries maintain consistent voltage output until depletion, unlike alkaline cells that gradually lose power. The CR2032’s coin shape also ensures a snug fit in Avital’s compartment design, reducing connection issues. Using incompatible batteries like CR2025 (thinner) or CR2016 (lower capacity) may cause erratic remote behavior due to poor contact or insufficient energy reserves.
Can Wrong Battery Polarity Damage an Avital Remote?
Yes. Inserting the battery upside-down disrupts power flow and may short-circuit the remote. Align the “+” symbol on the battery with the “+” marking in the compartment.

How Often Should You Replace an Avital Remote Battery?
Replace the battery every 12–18 months, depending on usage frequency. Extreme temperatures or frequent button presses accelerate drain.
What If the Remote Doesn’t Work After Battery Replacement?
Recheck the battery orientation, clean corroded contacts with rubbing alcohol, and ensure compartment closure. If issues persist, reprogram the remote using your vehicle’s manual instructions.
Expert Views: Redway’s Pro Tips for Remote Maintenance
“Always opt for branded lithium batteries—cheap alternatives risk leakage and voltage inconsistencies. For older Avital remotes, apply dielectric grease to contacts to prevent oxidation. If reprogramming fails, a factory reset (holding the ‘Lock’ and ‘Start’ buttons for 10 seconds) often resolves signal handshake errors.”

FAQ
- Q: Can I use rechargeable batteries in my Avital remote?
- A: No—rechargeables typically output 1.2V instead of the required 3V, causing malfunctions.
- Q: Does opening the remote void Avital’s warranty?
- A: Only if internal components are damaged during the process. Battery replacement alone is warranty-safe.
- Q: How do I dispose of old CR2032 batteries?
- A: Take them to a lithium battery recycling center—never incinerate or landfill them due to toxic metal content.
