How to Replace the Key Battery of the Citroen C3

Model: Citroen C3 SC - Years 2009-2016
Part: Key

If pressing the lock and unlock buttons on the remote key does not open or close the locks, it is likely that the remote battery (model CR 1620) has run out. Replacing it is straightforward and does not require special precautions. Locate the slot on the back of the remote to lever apart the two halves: the half containing the buttons also houses the electronic circuit with the battery. Once you have removed the circuit, take out the old battery and insert the new one in the same orientation.

How to Check the Oil Level on a Jeep Renegade?

To check the oil level on a Jeep Renegade, you need to open the bonnet to access the components inside the engine bay: on the lower left side of the engine block, you will find the dipstick for checking the level. This should be pulled out and thoroughly cleaned with a cloth: once cleaned, reinsert it back into its tube and pull it out immediately after. This way, you can check that the oil mark is between the minimum and maximum levels; finally, you can place the dipstick back in its tube.
