With display	CR2450	620–650	1.5–2 years
Both types	CR2026 (not recommended)	160–170	6–12 months

Please note: batteries CR2026 They are physically fit in size, but because of the smaller capacity, they will last a maximum of six months. Also avoid cheap unlabeled counterparts – they can leak and damage the keyboard.

2. Key with display

This process is more complicated and requires caution:

1. Remove the metal key (as in the standard version).
2. On the back cover, find two small indentations - insert plastic blades into them and gently separate the body.

4. Battery CR2450 It is under a metal lock. Carefully put a screwdriver on it and take it off.
5. Replace the battery by observing polarity (marked on the board).
6. Install the lock back, connect the halves of the case and check the work.

If the display does not turn on after replacing or shows an error, there may have been a synchronization failure. In this case:

1. Get into the car and close all doors.
