| Car does not begin, however remote buttons work. | Damaged or cracked transponder coil/antenna inside the card. | Open the card and resolder the micro-coil; look for hairline fractures. |
| Total failure (no start, no remote functions). | Deep battery discharge, overall internal circuit board failure, or lost pairing. | Change the battery, examine the circuit board, or reprogram with an OBD2 tool. |
| Buttons require heavy pressure to work. | Worn-out micro-switches or misalignment below the plastic housing. | Replace the internal micro-switches or tidy the contact points. |
| Physical damage (cracked housing). | Drops, flexing in pockets, or basic wear and tear. | Purchase a replacement empty shell casing and transfer internals. |
